Transvaginal scans use probe transducers inside the vagina to generate sonogram images, and standard ultrasound produces 2-D images using a transducer over the abdomen, states the American Pregnancy Association. Advanced ultrasound works similarly to the standard ultrasound but targets a suspected problem. Doppler ultrasound measures slight changes in the frequency of the ultrasound waves, 3-D ultrasound generates 3-D images of the developing fetus, and 4-D ultrasound uses scanners to look at the face and movement of the baby. Fetal echocardiography assesses the baby’s heart anatomy and function.
