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 TestThe 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.
