Your doctor has ordered a stress test with Cardiolite enhancement. Cardiolite is a radioactive tracer that is used to assess the blood flow to your heart muscle as well as the strength of the heart muscle. This information, in combination with your EKG portion of your stress test, will assist your doctor in better determining a course of treatment.

Upon arrival you will register at check in. A certified nuclear medicine technologist will then prepare you for the test. An IV will be started and you will be given a small dose of Cardiolite. There is a delay of ½ to 1 hour before you are scanned to allow the tracer to be absorbed. Then you will lie on the imaging table for approximately 15 minutes while the camera takes pictures around your chest.

After the first set of pictures, you will be prepped for the stress test portion of the exam. If your doctor has ordered or you are unable to walk on the treadmill, you will be given medicine (Dobutamine or Adenosine) so that pictures can be taken of your heart at stress.

Another set of pictures will begin approximately 30 to 45 minutes after your stress test. This will take approximately 15 minutes.
