How is a Nuclear Medicine Exam different from other x-ray Exams?
X-ray exams usually show the structure of an organ. A Nuclear Medicine Exam shows how an organ is functioning. For example an x-ray exam is used to see if there are any abnormalities in the structure of a Gall Bladder. The Nuclear Medicine Exam reveals if the Gall Bladder is functioning properly by watching it for a period of time to determine if it is excreting bile normally.
