When a patient is unable to walk on a treadmill, can be used as a substitute for exercise. Your EKG and blood pressure will be monitored before, during, and after the drug infusion. Nuclear images will be taken at rest and after the medication infusion.

What to Expect

This test has two parts:

In the Nuclear Medicine Department you will receive an injection of a radioisotope. There will be a resting period to allow the radioisotope to circulate then nuclear images will be obtained. 

The second part of your test, in Cardiac Imaging will entail obtaining a brief health history, completing consent forms, setting up for an EKG, having an IV inserted, and receiving the medication ordered by your physician. You will then receive a second injection of the radioisotope. Again, there will be a resting period to allow for circulation of the radioisotope.  The test will conclude with a final set of nuclear images. The total test time will be approximately three hours. The results of your test will be available to your physician within 24 hours.
