Brain Tumor Imaging with thallium and MIBI

You have been scheduled for a brain tumor scan, which involves the use of a small amount of radioactive material. The level of radioactivity used is extremely low and has no side effects.

Preparation for the procedure:
There are no pre-exam instructions. 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:
Once in the scan room an IV will be placed in a vein in your arm. Two radioactive tracers will then be injected through the IV. A SPECT scan will then be performed. For this you will be lying down on a table and two or three detectors will rotate around your head and make three dimensional images. A second SPECT scan will be performed. Each scan takes about thirty minutes. Claustrophobia is not usually a problem. This gives the doctor information similar to a CT or MRI.

The images will be reviewed and the results will be sent to your physician. Your physician will discuss these results with you and explain what they mean in relation to your health.
