Gestational Sac (GS)
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.
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.
First trimester ultrasound scanning can diagnose many different issues in pregnancy.
Want to know the age-old question of "how many weeks pregnant am I?" Some simple rules of thumb can also be effectively used.
Unlike ultrasound imaging used to give parents a picture of baby in-utero, Doppler ultrasound is used to view blood flow in the fetus.
Fetal ultrasound measurements can show how the baby is growing and detect abnormalities. During pregnancy many different ultrasounds measurements can be done.
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.
During the first trimester of pregnancy, major changes takes place in fetal development. Read about the first 12 weeks of human development, week by week, and see what happens to your baby!
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.
One of the most important reasons for prenatal visits and for doing an ultrasound examination is to estimate the fetal size of your baby.
You may have had a positive pregnancy test but when will you be able to have an ultrasound to confirm the pregnancy? And what will that early ultrasound show?
When can the fetal heart beat be seen first on ultrasound?
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.
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?
While ultrasound and Doppler fetal ultrasound heartbeat monitors are used by healthcare professionals throughout pregnancy, could the non-medical use of these devices be doing harm?
Some women are concerned when the fetus measures size-wize different on ultrasound when compared to their expected due date.
Ultrasound pictures are routinely done on most pregnant women. Below are two pictures. Try to identify what they show, then answer the quiz on the next pages.
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.
The placenta is the organ that supplies all the oxygen and nutrients the growing fetus needs.
A fetal echo or fetal echocardiography is an ultrasound test performed to evaluate the heart of the fetus during pregnancy and is often done as early as 20-24 weeks or later in pregnancy.
The amount of amniotic fluid is measured either by checking the largest pocket of fluid by ultrasound or by measuring the largest amniotic fluid pocket in each of four quadrants and then adding those up. This is called the AFI or Amniotic Fluid Index.
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.
Grading of the placenta can be done by ultrasound and by looking and how much calcifications there are in the placenta. A grade 3 placenta, for example, is normal at 40 weeks.
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.
I am on CD10. Uterine lining is 6mm, E2 4276, P4 .49, LH 9.9. I have 23 follicles. I am also on estrogen. What is next? I'm not sure if my levels are good. I do know my lining is not thickening, which I know that will cause a canceled transfer. Can someone explain or help me? Also I am triple layered.
The trusted transducer ultrasound is likely going to be a part of your prenatal check-up, but there may be a few additional ultrasounds in order that you will want to know about.
