A fetal ultrasound or sonogram is a test that uses high-frequency sound waves to produce images of the developing baby in the uterus. This fetal imaging tool can accurately determine gestational age, fetal number, viability, and placental location. It is used to monitor fetal health and development, detect any congenital abnormalities or other potential problems, and help confirm a diagnosis. Ultrasound is an important component of obstetrics medical billing and physicians need to report services correctly to ensure accurate reimbursement. While fetal abnormalities are generally rare, the American College of Radiology and the American Institute of Ultrasound in Medicine recommend that the following structures should be evaluated for defects during a routine prenatal ultrasound:. The first fetal ultrasound is typically performed during the first trimester to confirm the pregnancy and estimate the length of the pregnancy.
The Dating Ultrasound
What to expect at your six-week ultrasound appointment
I just called a OBGYN office to make an appointment for my first and only ultrasound during my pregnancy, and the lady on the phone called it "dating ultrasound". When I asked her what it means, I didn't get a clear answer from her. Then I called and asked again, still I don't get an answer what it is. Please help, what does the "dating ultrasound" mean? Thank you so much all.

It is now considered by many to be the most valuable diagnostic tool in the field. Ultrasound was first used clinically in pregnancy in the early s to measure the biparietal diameter BPD —the distance between spikes on an oscilloscope screen. Since then, the technology has progressed to the point that even relatively inexpensive ultrasound machines yield detailed real-time images of the fetus. This chapter addresses general aspects of ultrasound in pregnancy as well as the use of ultrasound to diagnose birth defects. More detailed discussions of other specific pregnancy problems that include ultrasound assessment—such as multiple gestation, third-trimester bleeding, and cervical insufficiency—are covered in other chapters.
