Nuclear Medicine > Exams & Procedures> Systemic Shunt Scan

This scan surveys the delivery blood throughout your body. This test may have been ordered by your doctor because they think that blood may be shunting (crossing tissues) in different ways than they would normally expect.

This test involves the injection of a radioactive tracer that localizes in the body according to how blood is flowing. Pictures are taken from head to toe and at various angles around the chest.

Preparation

  • Bring a list of all medications and supplements you take. This includes vitamins, herbal remedies, and holistic medications.
  • Do not bring children or pregnant women with you to the department. We do not want to expose them to unnecessary radiation.
  • Any of these procedures are subject to change according to the discretion of the nuclear medicine physician. The test duration is a rough estimate. Please be aware that the time may be lengthened if the scan has to be repeated, if emergency cases are brought to the department or due to unforeseen circumstances.

About the Procedure

  • A technologist will briefly explain the test to you and try to answer any questions you may have about the procedure.
  • A technologist will ask you a few questions about your medical history and medications.
  • You will be asked to lie down on the imaging bed and a technologist will inject a small amount of a radioactive tracer into a vein.
