Nuclear Medicine

Nuclear Medicine Service

Nuclear Medicine provides a full range of advanced accredited functional imaging and therapy services for the Veterans Affairs North Texas Health Care System, including General Nuclear Medicine, Nuclear Cardiology, Nuclear Medicine Therapy, Positron Emission Tomography (PET), Single Photon Emission Computed Tomography (SPECT) and bone densitometry (DXA).

What is Nuclear Medicine?

Nuclear Medicine is a medical specialty that uses radiotracers (radioactive drugs) to diagnose, treat, and evaluate the response to treatment for many health conditions. These radiotracers may be administered through different routes, but are most commonly given intravenously (within a vein), inhaled, or swallowed to investigate the function of various organs or body systems. Specialized scanners are used to produce the images needed to make a medical diagnosis.
