    What is the difference between a nuclear medicine scan and a PET scan?

    I am having a pet scan next week to see where this might be, I have never had one. How is it different than the nuclear medicine scan, like I had before?

      Actually, a PET is a nuclear medicine test. A nuclear medicine test will show function, not anatomy like a CT will. Some patients will get a PET-CT and this is where the image of a PET is laid over the image of a CT so that your doctor can see both function or activity as well as the anatomical sight. Nuclear medicine is any test where a radio-isotope is administered into the body so that the radiation is in the body and a scan picks it up instead of a radiation beam directed into the body from an outside source. The PET machine is like a camera that detects the isotope within you. I hope this helps to answer your question. Best of luck to you, Carm RN.

      So your Dr. didn't tell you that you originally had a Pet scan? They didn't request the last Pet scan in order to compare it to this one?

      A pet scan is fairly easy....other than the fasting required. I hope it is an early scan so you can eat! It is easy....just relax. I reccomend that you wear clothes with NO METAL, then you can stay in your clothes. Hang in there!
