Question

Answer 1

An ultrasound is the machine that allows you to see your baby during your pregnancy. A sonogram is the picture taken of your baby during the ultrasound. A sonogram is a "still-shot" of your baby. 4D Ultrasounds take 3D ultrasound images, or 3D sonograms, and adds the element of time to the process. The result: Live Action ultrasound images of your baby. Some people refer to the procedure as prenatal imaging, 3D imaging, a 3D scan, or 4D scan.

Answer 2

My OB told me the names are interchangable they are the same thing, just as some OBs refer to them as a scan.
