I am a long time med/surg floor nurse. But this question from a friend stumped me. What is the difference between getting an ultrasound versus getting a sonogram? It came up in a conversation about ultrasounds for pregnancy and the friend said something along the lines of "aren't they really sonograms or did they use to do sonograms for pregnancies, or what is the difference." I had no idea. I looked on the Internet and the answers were all over the place. Yes there is a difference (with technical details), to no there is no difference. One answer said it is like calling it an automobile versus calling it a car?I don't I want the answer to be too technical! I believe in the KISS form of explanations.
