Nuclear Medicine

Nuclear Medicine – Nuclear medicine procedures show physiology (function), opposed to most traditional imaging modalities showing anatomy. Nuclear medicine procedures use a pharmaceutical that has been labeled with a radionuclide (radiopharmaceutical) and is used for the diagnosis and treatment of disease. This is not X-ray contrast material (dye). The radiopharmaceutical is administered to the patient by injection, orally, inhaled, or ingested with food. Nuclear medicine uses a camera called a Gamma Camera interfaced with a computer. The administered radiopharmaceutical gives off gamma rays from the targeted organ; the camera detects the emitting gamma rays and stores them in the computer.

What to Expect

The patients lie on their back on an imaging table. A series of images with the camera rotating around the patient or table moving out of the camera are acquired, the patient will need to remain still. The camera moves very close to the body and is necessary to obtain the best quality images. Our camera has two camera heads, one over the table, and one under the table, both sides are open. Sometimes an IV line needs to be inserted for administering the radiopharmaceuticals. The technologist will call you the day before to confirm, prepare, and explain the procedure.

The length of time for nuclear medicine procedures vary greatly, depending on the type of exam; actual scanning time may take 20 minutes to several hours.

Preps will vary depending on the specific exam and will be discussed when the technologist calls to confirm appointment.
