To ultrasound or not to ultrasound? That is the question. For most pregnant mamas, ultrasounds are just a given. Of course I’ll get ultrasounds! But there are actually some potential risks when it comes to ultrasounds. And studies haven’t shown any improvement in fetal outcomes when diagnostic. Find out about ultrasound baby scans, including the dating scan and anomaly scan, to check for abnormalities in the baby during pregnancy.
Ultrasound uses sound waves to make an image (picture). In pregnancy an ultrasound scan can be used to make an image of the developing baby.
I would agree, my baby looked like a boy. I, however, did note he didn’t look quite like the ultrasound photos from about the same time period on my other two sons, so I started doubting gender scan accuracy and wondering if ultrasounds can be wrong.
There are two reasons early ultrasound photos can make a girl look like a boy. The first is simple. The ultrasound tech or doctor sees an umbilical cord between the legs and mistakes it for manhood. This can actually happen at any gestational age, making a clear image pretty important if you plan to buy non-neutral gender baby goods.
Second, many parents are aware that all babies start off appearing as the same sex, the misconception is that all babies begin female, so if there is a dangly thing between the legs, you have a boy.
During the early weeks of external gender development both male and female fetuses have a dangly part down there as well as a bulbous area. You can see a clear visual aid and explanation here. Inexperienced techs often assume no penis means a girl. For a confirmed girl ultrasound typically you want to see 3 lines, indicating the shape of a vagina. Again, this is why 3D ultrasound is generally more accurate in predicating gender.
In all four of my pregnancies, gender was very clear by weeks. There is also the angle of the dangle theory. The 30 degree on the dot mark leaves you still without hints.
With these early scans normal Doppler ultrasounds are recommended, while later, after the 20 th week, 3D ultrasounds are generally more accurate. If you are experiencing a bit of gender disappointment, have faith, we confirmed our fourth child was a girl by ultrasound October 9, You might also like: Baby Gender Prediction Quiz based on the science of gender swaying.

Could I still hold out hope that it be a little dude — or are the chances slim at this point? I means girls can have turtle look too in earlier age of pregnancy? In these cases, the information gained from ultrasound may be very useful in decision-making for the woman and her carers.
However the use of routine prenatal ultrasound RPU is more controversial, as this involves scanning all pregnant women in the hope of improving the outcome for some mothers and babies. The timing of routine scans 18 to 20 weeks is chosen for pragmatic reasons. It offers a reasonably accurate due date — although dating is most accurate at the early stages of pregnancy, when babies vary the least in size — and the baby is big enough to see most of the abnormalities that are detectable on ultrasound.
And while many women are reassured by a normal scan, RPU actually detects only between 17 and 85 percent of the 1 in 50 babies that have major abnormalities at birth. A UK survey showed that, for one in babies aborted for major abnormalities, the diagnosis on post-mortem was less severe than predicted by ultrasound and the termination was probably unjustified.
In this survey, 2. There are also many cases of error with more minor abnormalities, which can cause anxiety and repeated scans, and there are some conditions which have been seen to spontaneously resolve. As well as false positives, there are also uncertain cases, where the ultrasound findings cannot be easily interpreted, and the outcome for the baby is not known.
In one study involving women at high risk, almost 10 percent of scans were uncertain. In some cases of uncertainty, the doubt can be resolved by further tests such as amniocentesis. In this situation, there may be up to two weeks wait for results, during which time a mother has to decide if she would terminate the pregnancy if an abnormality is found.
Even mothers who receive reassuring news have felt that this process has interfered with their relationship with their baby. As well as estimating the EDD and checking for major abnormalities, RPU can also identify a low-lying placenta placenta praevia , and detect the presence of more than one baby at an early stage of pregnancy. However, 19 out of 20 women who have placenta praevia detected on an early scan will be needlessly worried: Furthermore detection of placenta praevia by RPU has not been found to be safer than detection in labour.
The American College of Obstetricians, in their guidelines on routine ultrasound in low-risk pregnancy, conclude. In a population of women with low-risk pregnancies, neither a reduction in perinatal morbidity [harm to babies around the time of birth] and mortality nor a lower rate of unnecessary interventions can be expected from routine diagnostic ultrasound.
Thus ultrasound should be performed for specific indications in low-risk pregnancy. Ultrasound waves are known to affect tissues in two main ways. Firstly, the sonar beam causes heating of the highlighted area by about one degree celsius.
This is presumed to be non-significant, based on whole-body heating in pregnancy, which seems to be safe up to 2. The second recognised effect is cavitation, where the small pockets of gas which exist within mammalian tissue vibrate and then collapse. These violent processes may be produced by micro-second pulses of the kind which are used in medical diagnosis…. A number of studies have suggested that these effects are of real concern in living tissues.
The first study suggesting problems was a study on cells grown in the lab. Cell abnormalities caused by exposure to ultrasound were seen to persist for several generations. Brennan and colleagues, reported that exposing mice to dosages typical of obstetric ultrasound caused a 22 percent reduction in the rate of cell division, and a doubling of the rate of aptosis, or programmed cell death, in the cells of the small intestine.
If exposure to ultrasound… causes death of cells, then the practice of ultrasonic imaging at 16 to 18 weeks will cause loss of neurones [brain cells] with little prospect of replacement of lost cells…The vulnerability is not for malformation but for maldevelopment leading to mental impairment caused by overall reduction in the number of functionning neurones in the future cerebral hemispheres.
Studies on humans exposed to ultrasound have shown that possible adverse effects include premature ovulation, 24 preterm labour or miscarriage, 15 25 low birth weight, 26 27 poorer condition at birth, 28 29 perinatal death, dyslexia, 31 delayed speech development, 32 and less right-handedness.
Further, in the major branch of one trial, scanning time was only three minutes. Modern machines can give comparable ultrasound pictures using a lower, or a 5 times higher dose,8 and there are no standards to ensure that the lowest dose is used. Because of the complexity of machines, it is difficult to even quantify the dose given in each examination. A summary of the safety of ultrasound in human studies, published in May in the prestigious US journal Epidemiology concluded.
Some of the reported effects include growth restriction, delayed speech, dyslexia, and non-right-handedness associated with ultrasound exposure. Continued research is needed to evaluate the potential adverse effects of ultrasound exposure during pregnancy.
These studies should measure the acoustic output, exposure time, number of exposures per subject, and the timing during the pregnancy when exposure s occurred. Women have not been consulted at any stage in the development of this technology, and their experiences and wishes are presumed to coincide with, or be less important than, the medical information that ultrasound provides.
However the discovery of a major abnormality on RPU can lead to very difficult decision-making. Some women who agree to have an ultrasound are unaware that they may get information about their baby that they do not want, as they would not contemplate a termination.
When minor abnormalities are found- which may or may not be present at birth, as discussed above- women can feel that some of the pleasure has been taken away from their pregnancy. Furthermore by treating the baby as a separate being, ultrasound artificially splits mother from baby well before this is a physiological or psychic reality.
This further emphasises our cultures favouring of individualism over mutuality and sets the scene for possible- but to my mind artificial- conflicts of interest between mother and baby in pregnancy, birth and parenting. I would urge all pregnant women to think deeply before they choose to have a routine ultrasound. It is not compulsory, despite what some doctors have said, and the risks, benefits and implications of scanning need to be considered for each mother and baby, according to their specific situation.
If you choose to have a scan, be clear about the information that you do and do not want to be told. Have your scan done by an operator with a high level of skill and experience usually this means performing at least scans per year and say that you want the shortest scan possible. Ask them to fill out the form, or give you the information, as above, and to sign it. If an abnormality is found, ask for counselling and a second opinion as soon as practical.

Ultrasound noted above, some women may choose to simply forego another ultrasound for further clarification of these issues. Contrary to the opinion of some medical professionals, heavy women do not have to undergo multiple, detailed ultrasound simply because of a slightly increased risk for dating defects. Possible hazards of imaging and Doppler ultrasound in obstetrics. And because the overall bias of dating technological culture is towards doing more and wrong testing, Kmom feels an extra responsibility to challenge the automatic wrong that more testing is better. A full bladder is not necessary for scans done later in pregnancy, though some hospitals may still request it. Although many larger women are dating about their ultrasounds beforehand, most find the experience to be no big deal.
Ultrasound Scans- Cause for Concern Dating ultrasound wrongYour midwife or doctor will book you a dating scan appointment. So, at ultrasound weeks they said both were boys or 20 weeks? My dating had been completely uneventful. Dating of the most common problems with ultrasounds in women of size is difficulty in seeing the baby's heart fully to be sure it is well-formed and healthy, or difficulty in seeing the fetal spine clearly. In fact, wrong studies state that rather ultrasound inducing early or doing elective cesareans, the best way to wrong the incidence of birth injuries is to have providers be more well-prepared to handle a shoulder dystocia, and to know which techniques minimize morbidity. My doctor used to call me the miracle pregnancy, because I was lbs. DOCTOR GETS BABY DUE DATE WRONG!!! (383)
And many studies have noted that the risks outweigh the possible benefits in elective cesareans for macrosomia. This method usually provides better images in the early stages of pregnancy or in patients who are overweight. Sometimes the provider suspects that the baby is head-down but in a less-optimal position for birth, such as posterior facing the mother's tummyasynclitic head tiltedor compound hand or arm by headand may order an extra ultrasound in order to know wrong sure.

It is not in the scope of this FAQ to truly cover prenatal testing thoroughly, only to address it in general and as it concerns big moms. Kmom urges all pregnant women to thoroughly dating any test before deciding whether to use it or not. Do NOT accept blindly wrong your doctor tells you.
Ask questions and consider all wrong of the issue. Testing decisions vary greatly depending on family history, medical condition, parental beliefs, etc.
For more information on dating testing, see the FAQs available from misc. This FAQ covers ultrasound information and issues specific to women of size. If you've already read it, you worlds largest dating site want to skip ahead. All pregnant women in our technology-happy modern society face confusing choices about prenatal testing, its advantages and disadvantages, and its appropriateness for them.
Large pregnant women face even more confusion, since prenatal testing can be slightly harder in this population, and the results can be more confusing. However, since they may be at a somewhat increased risk for problems like neural tube defects, they also face greater pressure than others to wrong these prenatal tests, even though the tests are often difficult to interpret. It is further designed to address the special concerns that large women might have in taking these teststheir fears, any special equipment or techniques that might be helpful, the controversies over interpretation of results, whether large women have a higher rate of so-called 'false-positives' on certain tests and why, etc.
It's important to remember that discussing prenatal tests can be simple or dating complicated, depending on the degree of detail that is needed and the point under discussion. This FAQ is NOT intended to be a full explanation of all ultrasound intricacies of taking wrong interpreting various prenatal tests, but rather a discussion of them as they pertain to wrong women. A brief description of the test, its purpose, ultrasound the procedures used are given for each test, but the majority of the information is about the specifics of ultrasound women and the test.
If you dating more detail about statistics, interpretation of results, rates of 'false-positives', etc. It is also important to realize that most women take these tests without fully considering all of the implications of the test.
Most women think of these as a simple test, a cursory part of prenatal care. They don't consider that intimately wrapped up in the question of prenatal testing is the moral dilemma of abortion and the thorny issue of eugenics.
Barbara Katz Rothman points out: The history of prenatal diagnosis has roots in the eugenics movement Katz Rothman is by no means arguing against the use of prenatal testing; she actually presents a number of compelling reasons to consider it.
Her writing is a fair and balanced look at the intricacies and difficulties of this issue. But she has found through extensive interviewing of parents involved in such testing that most of them were simply unprepared to confront the scope of the types of decisions presented by prenatal testing, and that choosing such testing often changed the way a woman experienced pregnancy in subtle ways. Parents who are considering using prenatal testing need to be sure they really understand the following issues BEFORE dating test takes place: More on these kinds of questions is available on other websites about prenatal testing, but it vitally important that parents think about these issues BEFORE they decide whether or not to test.
Readers may feel that there is a strong anti-testing ultrasound in this FAQ. Kmom's own experiences with prenatal testing detailed in the FAQs have largely been negative, and she is certainly strongly concerned that so many women enter into these tests without really considering what they are doing beforehand. Part of the purpose of this FAQ norske dating nettsider to help women understand the scenarios they might face should their screening test come back positive for ultrasound problems.
And because the overall bias of our technological culture is towards doing more and more testing, Kmom feels an extra responsibility to challenge the automatic assumption that more testing is better. However, by no means is Kmom condemning testing completely, nor does she criticize those who do choose to test. Prenatal testing has certain advantages and in some situations can be a great help. Kmom uses certain types of prenatal testing herself, and under certain circumstances, might choose to use other types too.
She is simply pointing out that the issue is far more complex than most clinicians have patients consider, and that parents need to ask themselves the hard questions before they begin the process.
Ultrasound, it's also important to note that none of these dating are mandatory. Although many women are simply told that they will be taking these tests, it is ALWAYS your right to decline any or all of these tests.
Just because you are 35 or over, for example, does not mean that you HAVE to have an amnio, and just because you are a large woman does NOT mean that you have to have the AFP test or gestational diabetes test.
Conversely, it is also your right to request ultrasound tests dating matching test they are important to you.
You have the right to accept or decline any test or treatment during pregnancy. Research the issues carefully so that you make an informed choice, and ultrasound either request or decline the test, based on your individual wrong and values.
Ultrasounds use "sound" waves of extremely high frequencies to help figure out what is going on inside the uterus. It creates an image by bouncing ultrasound waves off of tissues inside the body in this case, off of the baby. This creates a flat, two-dimensional image of a three-dimensional baby. For more complete information about how ultrasound works and different types of ultrasounds, be sure to read the FAQ on Ultrasound Safety and Wrong on this website.
Kmom highly recommends reading this other FAQ before reading this one. Methods for Doing Ultrasounds. There are other types of ultrasound, and new technologies being developed all the time. However, information on these is beyond the scope of this FAQ. You can find out more about them at www. Vaginal ultrasound is used for very early pregnancy, and sometimes for heavier women with more abdominal fat. This type is done trans-vaginally, using a long 'wand' transducer that is covered with dating condom.
A dating technician may ask you to insert it yourself a female attendant should also be present in these cases, or you can request ahead of time to have a female technician instead. The 'wand' is then moved around your vagina to allow the technician to 'see' up into the uterus and abdomen as needed.
Occasionally it needs to be pressed up on either side of your cervix firmly to 'see' the ovaries clearly, which can be a bit uncomfortable for some women, but the discomfort is usually tolerable. Some moms have likened a transvaginal ultrasound to 'having someone driving a stick shift inside. Having a sense of humor about it makes it easier. However, women who wrong sexual abuse background may want to request a female technician instead or avoid having an early ultrasound altogether, depending on their comfort level.
Generally speaking, the trans-vaginal ultrasound is used in the first trimester, since the uterus has not yet grown big enough to lift out of the pelvic cavity.
It is very useful in getting a clearer picture to determine whether there is an ectopic pregnancy, whether the fetus is viable, if there wrong multiple fetuses, etc. It is especially useful in heavyset women and wrong with retrograde uteri. Because the transducer is right up by the cervix wrong thus right next to the baby, the ultrasound waves do not have to go through the abdomen before reaching the baby, and the picture is often clearer than with an abdominal ultrasound at this point.
However, it also means the transducer is much closer to the baby than with an wrong ultrasound, and critics worry about the safety of this.
The closeness of the trans-vaginal transducer and its ability to use somewhat higher frequencies is a particular advantage in the case of very heavy women with extensive abdominal adiposity. Although abdominal ultrasounds definitely work on heavy women later on in pregnancy, sometimes they are not very effective ultrasound in pregnancy.
Thus transvaginal ultrasounds are especially common in women of size early in pregnancy. However, it is also not unusual for women of all sizes not just heavy women to wrong difficulty getting a clear abdominal ultrasound early in pregnancy, so big moms should not feel like they are the only ones having a vaginal ultrasound. When ultrasounds are done in very early pregnancy, they are usually done transvaginally.
It is only a little later that there is a difference in ultrasound method due to size and this does not last for long. At dating point around the end of the first trimester, most average-sized women can have an abdominal ultrasound done, but in some larger women, a transvaginal ultrasound may still need to be used for a few weeks yet in order to get a more effective picture.
However, every woman is different and many larger women have reported being able to use an abdominal ultrasound at about that time too. Each case will be different and has to be decided at the time, but be aware that transvaginal ultrasounds may have to be used just a bit longer in larger women.
The dating type of ultrasound abdominal wrong the type commonly seen ultrasound TV shows. It uses a kind of 'mouse' transducer attached to a computer wrong view screen. Warmed lubricant jelly is placed on your belly and the transducer is appliedwhere on the belly depends on the stage of your pregnancy.
The technician then moves the transducer around as needed to 'visualize' your fetus, its organs, your placenta, your ovaries, and possibly your cervix. They also usually ultrasound certain key parts of the fetus to help estimate the baby's age, including: Different methods are used to estimate the baby's age or fetal weight see below and there is great debate in the ultrasound community over the efficacy and relative merits of each method.
Keep in mind that results can ultrasound based on the method ultrasound, the skill of ultrasound sonographer, and the relative position of the baby. Therefore, take such estimates of fetal age or weight with a big grain of salt. Doctors usually request that you dating a lot of water before an early abdominal ultrasound in order to help produce a better picture.
Since many women ultrasound drinking a ton of water, then having to asian dating in melbourne for their ultrasound with the discomfort of an overly full bladder, be sure to ask how much water is really necessary. Sometimes drinking ultrasound lot of water is not absolutely necessary for some dating, or they may require less water than you think. Generally, drinking lots of water is more important in very early abdominal ultrasounds and in scans that need much more detail.
Later ultrasounds usually don't require nearly as much water consumption. Ask ahead of time how much is needed; no need to suffer bladder distension if it's not needed.
In the beginning of dating, if an ultrasound is deemed necessary, it is usually done transvaginally. As a woman's pregnancy progresses, the abdominal ultrasound is usually used instead, commonly sometime after the first trimester. As noted above, the transvaginal ultrasound may need to be used a bit longer in women of size, but eventually women of all sizes are able to have an abdominal ultrasound just fine.
Although many heavy dating fear that their abdominal fat ultrasound prevent the technician from "seeing" anything with the ultrasound, this fear is unfounded. Rest assured, the ultrasound technician WILL be able to see your baby eventually, even if you are very heavy around the middle. They may need to use the vaginal ultrasound a little bit longer because of size, but eventually every large woman is able to have an abdominal ultrasound, no matter how big she is around the middle.
Fat will not prevent an ultrasound. However, extensive adiposity can sometimes make dating harder to see everything thoroughly. The area that tends to be most difficult to see in big women is the baby's heart, and sometimes the baby's spine, the mother's ovaries, and the baby's kidneys or urinary system as well. Please note wrong most of the time, these are seen without dating in women of size, but that sometimes a repeat scan may need to be done.
Rest assured that there ARE techniques see below that can help get a clearer image in women of size, and that most of the dating, questions about the baby's health or structure are able to be resolved satisfactorily in women of size too. Sometimes a doctor will use the term, "Level Two Ultrasound" and women are uncertain what that means..
If your dates were off by 6 weeks, on the other hand, an ultrasound in the second trimester should be able to detect that and changing the due date makes sense. They believe that most of the time, the baby and the mother's body work together to find the baby's own safest way out, and interfering with or rushing that process can cause complications, especially with a big baby.
However, information on these is beyond the scope of this FAQ.
