Time required:
1 hour

Purpose:
Brain SPECT permits physicians to visualize brain function by obtaining three dimensional images of the brain.

Preparation:
Brain scans do not require fasting, special diets, or medication.

Test Procedure:
A radiopharmaceutical will be injected into a vein in your hand or arm. The technologist will then have you lie down on your back on a padded examination table.
After lying down on the table, the camera, capable of imaging the areas of your brain where the radiopharmaceutical has accumulated, will be moved near your head.
The closer the camera is to your head, the better the images of the blood flowing in your brain will be.
The images last approximately 30 minutes, and you must lie completely still (sedation may be required).
The images will be interpreted by a radiologist and results sent to your doctor.
