DISIDA Scan

A DISIDA scan is performed to visualize the gall bladder filling and emptying. Patients with pain in the right upper quadrant of the belly and/or nausea may receive a DISIDA scan to evaluate the gall bladder.

Your Medical Test

The patient receives an injection of Kinevac to help the gall bladder contract, followed by an injection of 99m-Technetium-DISIDA in a vein in the arm. Images are obtained for one hour.

Technetium-99 is a widely-used isotope in Nuclear Medicine. It has a short half-life (6 hours) so that the material soon leaves body tissues. The technetium is attached to a pharmaceutical agent (DISIDA) that permits visualizing of the gall bladder. No allergic reactions are experienced with this test.

Images from a normal hepatobiliary scan showing liver (early), the gall bladder filling (dark area) and the tracer emptying into the small bowel.

How to Prepare for a DISIDA Scan

  • You should continue to take any regularly prescribed medications.
  • Your should wear comfortable clothes for the procedure. The technologist will need to be able to inject the isotope in a vein at the elbow.
  • The exam will take about two hours.
