You can screen for Down syndrome by ultrasound as early as 11-12 weeks. Screening is done with an ultrasound examination and two blood tests, and it can detect up to 90% of Down syndrome fetuses.
The growth of the fetus (and the percentile of the ultrasound sonogram) during pregnancy is dependent on many factors. Check your baby's fetal growth with this handy chart.
As pregnancy progresses you can make the pregnancy diagnoses seeing several landmarks where you would normally expect to see the pregnancy development.
There are many parts of the uterus, placenta, amniotic fluid, and the fetus examined during the anatomic ultrasound examination around 20 weeksa of the pregnancy.
During pregnancy many different ultrasounds measurements can be done. They can include the crown rump length (CRL), biparietal diameter (BPD), femur length (FL), head circumference
An ultrasound in pregnancy can be either done as a 'routine' anatomy ultrasound, usually between 18-20 weeks or it is done for specific reasons which usually depend on the time of pregnancy.
Ultrasound of the embryo and fetus before 14w0d of the pregnancy is the most accurate method to establish the pregnancy estimate due date (EDD). The crown-rump length (CRL) before 14w0d is accurate within 5-7 days of the actual due date. The earlier the CRL is done in pregnancy, the better the actual estimated due date can be calculated.
When the pregnancy hits the 20th week of gestation, an anatomy ultrasound is often ordered. This ultrasound is used to determine fetal anomalies, the baby's size and weight, and also to measure growth to ensure that the fetus is developing properly.
Women with high-risk pregnancies and those who experience other complications often need a close watch of the fetus for potential problems or complications.
First trimester ultrasound scanning can diagnose many different issues in pregnancy.
The fetal crown rump length (CRL) is the measurement between the top of the head to the area above where the legs begin.
Up to one in three women experience vaginal bleeding during the firest few months of the pregnancy, and many wonder how they can make sure the pregnancy is viable.
Occasionally a so-called 'echogenci focus' or bright spot is seen in the heart of the fetus. Does this suggest an increased risk of Down syndrome in the baby?
The gestational sac is the structure surrounding the fetus early in pregnancy and its shape early in pregnancy (usually before 8-10 weeks) is important.
Pregnancy can be a difficult time for the whole family but especially children. Here are 12 steps to make it easier.
Mother-in-laws can be helpful or not when you are pregnant. Read how to deal with your MIL in 12 steps.
A sonogram done several days before ovulation can sometimes determine if the "leading follicle" (the area in the ovary where ovulation will happen from) is in the right or the left ovary. This can usually predict where ovulation may happen.
An ultrasound (or sonogram) examination in pregnancy is a medical procedure that uses high-frequency sound waves to scan a person creating pictures (sonograms) of the organs being examined.
An ultrasound or sonogram during pregnancy is used to assess the development of the fetus and to look at other structures such as the uterus, ovaries, and cervix.
IVF in-vitro fertilization is defined as a procedure when eggs are removed from the ovary, fertilized outside the body and then implanted into the uterus.
Q: I am 5 weeks and 4 days pregnant. I just had a sonogram done and the doctor told me she could not see the corpus luteum.I know the corpus luteum is necessary to produce enough of progesterone to support the pregnancy. Is it a problem? Is my pregnancy progressing well or in danger?
Around 11-12 weeks many doctors perform a transvaginal sonogram to measure the fetal neck (nuchal translucency) to assess the risk of Down syndrome.
Choroid Plexus Cysts (CPC) are small fluid filled areas in the brain and they are a common ultrasound finding in the fetus during the 2nd trimester of pregnancy.
Hysterosonography is often used to investigate uterine abnormalities in women who experience infertility or multiple miscarriages.
With vaginal bleeding the risk of miscarriage is high before you see the fetal heart beat and low without bleeding after you see the heart beat
A missed abortion or miscarriage can be diagnosed on ultrasound (sonogram) with several different signs.
Most patients in the US get at least a basic sonogram around 18-20 weeks, though it may surprise you to find out that presently most medical associations do not recommend ultrasound in pregnancy.
There are several ultrasound markers for Down syndrome which can be seen on sonogram during pregnancy and which can possibly indicate an increased risk for the fetus having Down syndrome.
Most moms to be are anxious to see what the little one looks like and can hardly wait for the first sonogram performed between the 18th and 20th week of pregnancy.
We should start to routinely measure the cervix in the second trimester of pregnancy to reduce prematurity
There is now ample evidence that measuring the cervix with transvaginal ulttrasound can identify pregnancies that may be at risk for preterm labor and delivery and treating them with progesterone may decrease preterm labor and delivery.
Gynecologic and Obstetric Ultrasound is the use of high-frequency sound waves together with computer imaging to painlessly view the fetus and the pelvic organs.
Ultrasounds, often referred to as sonograms, are digital images taken of a fetus in-utero. Typically, a 2-D ultrasound is used to determine fetal growth, organ development and gender.
Although certain harmful effects in cells are observed in a laboratory setting, abnormalities in embryos and offsprings of animals and humans have not been unequivocally demonstrated in the large amount of studies that have so far appeared in the medical literature purporting to the use of diagnostic ultrasound in the clinical setting.
The following is a listing of indications for the anatomic ultrasound. An ultrasound can be of benefit in many situations in the second and third trimesters, including but not limited to the following circumstances.
