About Nuclear Medicine Nuclear Medicine FAQ Preparing for a Nuclear Medicine Exam Nuclear Medicine is a safe, painless and effective imaging modality that provides specific information about organ function and structure. Using very small doses of radioactive materials, comparable to that received during a diagnostic X-ray, metabolic information is obtained. Nuclear Medicine imaging is unique in that it records organ function and structure, instead of diagnostic radiology, which is based upon anatomy. It is a way to gather medical information that may otherwise be unavailable, require surgery or more expensive diagnostic tests. Nuclear medicine is a healthcare specialty involving the use of radioactive compounds to perform diagnostic imaging examinations. These examinations can lead to the effective treatment of many diseases. Cardiac Nuclear Medicine refers to these diagnostic examinations that result in images of the heart.
