What Happens During A Kidney Renal Nuclear Medicine Scan?

Before this test, you should tell your doctor if you are pregnant or nursing, and if you are on any medications.

During this test a "tracer" is injected into one of your veins. The tracer has a radioactive "tag" so that it can be followed in your body with special detectors. Right after the tracer is injected, the imaging will begin. A special gamma camera is used to track the radioactivity. Images may be shown on a PC screen and then stored on film.

This test is performed in a hospital or in a health care provider’s office by a nuclear medicine technologist. During this test, you will be on an exam table. You will be asked to lie still to keep the images from blurring.
