Myocardial Perfusion Study Resting with Thallium or MIBI

You have been scheduled for a resting thallium study, which involves the use of a small amount of radioactive material. The level of radioactivity used is extremely low and will not make you feel any different.

Preparation for the procedure:
There are no preparations for this procedure. Please inform the technologist if you are pregnant or breast feeding. The imaging may be changed, or special instructions given based upon that information.

What to expect: Thallium:
Once in the scan room you will be injected with Thallium in a vein in your arm. Ten minutes later you will be positioned on your back and a camera with two or three special detectors will rotate around your heart. This scan will take approximately twenty minutes. Four hours later a second twenty minute picture will be taken of your heart. Some patients require additional images twenty four hours later. These images will take approximately thirty minutes.
Alternatively, there is another machine called a D-SPECT that has nine detectors on it. With this machine you sit in a chair and the machine rests near your left side and chest. With this machine the first images takes about ten minutes. Some patients require additional images twenty four hours later.
