Nuclear medicine is a subspecialty within radiology. It comprises diagnostic examinations that result in images of body anatomy and function. The images are developed based on the detection of energy emitted from a radioactive substance given to the patient, either intravenously or by mouth. Generally, radiation to the patient is similar to that resulting from standard x-ray examinations.

Nuclear Medicine scans include Bone scan, Thyroid scan, V/Q scan, Cardiac scan, Pet scan.
