Persantin Sestamibi/Exercise Sestamibi Scan

A Persantin Sestamibi/Exercise Sestamibi Scan is used to examine the blood flow to the heart muscle before and after a stress test. This can determine any partial or complete blockages to the coronary arteries that supply the heart muscle with blood. It can also be used to determine relative heart function prior to surgery. However, there are many reasons why this test is performed and you will need to talk to your doctor about this.

The Procedure

  • The patient is given an intravenous injection of a radioactive material and imaging is performed 20 mins later for 15 mins. The patient is given a glass of milk to drink before the first images are performed.
  • Following a break of between 1-2 hrs, a stress test is performed under the supervision of a doctor and nurse. A second injection is given intravenously when the patient reaches their maximum exercise level.
  • After a 45 min break, during which the patient can have something to eat and drink, a second set of images is taken for 15 mins.
  • During the images, the patient is asked to lie with their arms extended above their head.
  • There are no side effects from the radioactive injections.
