What can I expect during the exam?

This exam is conducted by a specially registered technologist in molecular imaging.

You will be injected through an IV with a radio isotope that will be concentrated by the liver cells and excreted into the biliary system and into the small bowel.

Scans will be taken every 5 minutes for 90 minutes. The scanning process may take up to 180 minutes.

What can I expect after the exam?

Unless your physician tells you otherwise, you may resume your normal activities after your molecular imaging scan. If any special instructions are necessary, you will be informed by a technologist, nurse or physician before you leave the molecular imaging department.
