The Nuchal Translucency Screening can be both confusing and scary to a mom-to-be? The Nuchal Transluscency Screening, or NT, is a pre-natal ultrasound scan which assesses your babys risk of being born with certain illnesses, including chromosomal abnormalities like Down Syndrome and certain heart problems. If you choose to have an NT test, it will be performed during weeks 11 to 13 of your pregnancy. Heres how an NT works: An ultrasound technician will start by determining your babys gestational age by measuring him from crown to rump. Then, shell measure the thickness of the fluid under the skin at the back of your babys neck, the area known as the nuchal fold. When a baby has greater amounts of fluid built up in the nuchal fold, the clear space on the sonogram behind the neck is larger than average. Babies who have chromosomal abnormalities generally exhibit this build up of fluid, but not every baby who exhibits a buildup of fluid behind their neck will have an illness. A complete assessment needs to take into account several additional factors. In addition to the Nuchal ultrasound, most women will provide a blood sample for screening. The results of these tests, plus the babys gestational age and the mothers age, are all incorporated into the results. The mothers age is a factor because women who are older than 30 are significantly more likely to deliver a baby with Down Syndrome. Once you have the results, you will need your doctor to help you interpret them. Remember: The Nuchal Translucency Screening does not definitively say if there is a problem with your baby. Instead, an NT test shows youwith about 70 to 80 percent accuracy how likely it is that the baby has a genetic abnormality. If it looks like your baby may have a problem, your doctor might recommend that you undergo amniocentesis, which requires taking a sample of your amniotic fluid. But because amniocentesis comes with a 1 in 200 chance of miscarriage, many women choose not to undergo this step. A Nuchal Translucency Screening can provide critical information about your babys health. Ultimately though, how you use that information, and whether you want the test at all, is a personal decision.More »

Quick - how is having a baby like submarine warfare? If you said that submarines and doctors both use sonar technology, you move to the head of the class! An ultrasound is a procedure that uses high frequency sound waves to scan your uterus.Those waves are then translated into an image of your developing baby. This technology is very similar sonar, which is used to locate and map things which are underwater, like submarines or sharks. In the first trimester, your doctor may perform a traditional abdominal ultrasound... But more commonly, she'll place sound probes in your vagina for a transvaginal sonogram, which can provide a clearer picture early in pregnancy. During about the sixth week of your pregnancy, either type of ultrasound can confirm that you are indeed pregnant. Your doctor will be able to measure the baby's size at this point, and can therefore estimate its gestational age. If your baby's gestational age is a full 6 weeks, it might be possible to detect your baby's heart rate. This sonogram will also be able to check for an ectopic pregnancy, whereby a fertilized egg implants outside the uterus. During your eighth week, another sonogram is performed. By this time, you should see able to see the heart beating strongly. At any point during the first trimester, a sonogram may also be ordered to check for a suspected miscarriage. And while all of this can be scary, know that most babies are fine and there is no reason to believe that yours won't be, too!More »

Congratulations, you've hit the final stretch! Here's what your sonogrammer will be looking for this month. By week 24, your doctor will be able to use a sonogram to determine how your placenta is positioned. In most pregnancies, it will be high in the top of the uterus. Sometimes, however, a placenta will be "low lying," which can be a concern. That's because, if the placenta does not move up from the bottom of the uterus, it can cover the cervix and make delivery difficult. This is known as placenta previa. During the last trimester of your pregnancy, a sonogram will also be able to determine which way your baby is positioned. This is important in the weeks leading up to pregnancy, as the baby should be resting with his or her head down. A sonogram can confirm that this is the case, and can also show if the baby is breeched, or lying feet first. During the last trimester, though, sonograms will mostly be used to determine that the baby is growing appropriately. However, if your delivery is overdue by a week or more, a sonogram can also be ordered to confirm the well being of your baby.More »
