What You Can Expect

A nuclear medicine scan involves two or three phases, which means that you may need to come back once or twice after the initial phase is completed.

The first phase consists of the administration of the tracer (radioactive material).

The second and third phases involve obtaining the images or pictures. The time required will vary according to the test.

You may be connected to an EKG monitor, and you will lie on a table in the procedure room. An intravenous (IV) line will be started in the hand or arm.

During the procedure it is important to remain very still, as motion can interfere with the quality of the pictures.

You may be asked to change positions to obtain different views of the organ or structure. The staff will instruct you, and will be monitoring you continuously.
