Fetal Ultrasounds Offered in Lynchburg, VA
A fetal ultrasound provides you and your obstetrician with a first glimpse of your developing baby.
- A safe, painless and non-invasive test
- Typically performed between 18 and 22 weeks of pregnancy
- Used to confirm a pregnancy and its location
- Used to determine how a pregnancy is progressing, the baby's growth rate, age and sex.
- Used to determine location and development of the placenta
- Identifies possible fetal abnormalities
Types of Ultrasounds
- Standard - directs high-pitched sounds waves toward the baby, which bounces off tissues, organs and bones in the mother's body, including those of the baby in uterus. This creates black and white images on a monitor.
- Advanced or Targeted - used to further investigate a suspected abnormality identified by a standard ultrasound.
- Doppler - measures slight changes in the frequency of the ultrasound waves as they bounce off moving objects, such as blood cells.
How To Prepare
- Wear comfortable, loose-fitting clothing.
- Most likely the test needs to be done with a full bladder. For transvaginal ultrasound or those in late pregnancy, a full bladder usually isn't necessary.
What To Expect
- The examination usually takes 30-60 minutes DEPENDING ON THE TEST ORDERED.
- The patient is usually positioned on an examination table and clear gel is applied to the abdomen. This improves conduction of sound waves and eliminates air between the transducer, a small plastic device that sends out sound waves and records them as they bounce back, and your skin.
- The transducer moves back and forth over the abdomen, directing sound waves into the uterus and capturing the reflected sounds waves that are digitally converted into images.
- FOR TRANSVAGINAL ULTRASOUNDS, A SMALL TRANSDUCER IS PLACED VAGINALLY. THIS TEST IS REQUIRED FOR BETTER RESOLUTION OF EARLY PREGNANCIES AS WELL AS FOR CLOSER EVALUATION OF DEEP FEMALE ANATOMY SUCH AS THE OVARIES AND UTERUS. YOUR PROVIDER MAKES THE DECISION FOR THE BEST APPROACH TO BE USED.
