Nuclear Medicine scans are used to help assist your doctor in the proper diagnosis of diseases, tumors, infections, and other disorders by the evaluation of organ functions. These scans can show the sizes, shapes and positions of the organs. Unique to Nuclear Medicine scanning is that it will show the function of the organ as opposed to just a picture. Having this type of procedure done will help determine if the organ is functioning properly.
