Overview
Cholescintigraphy which utilizes technetium-labeled hepatic 2,6-dimethyl-iminodiacetic acid (HIDA) may be helpful in the diagnosis of acute cholecystitis. Findings on a cholescintigraphy diagnostic of acute cholecystitis include lack of visualization of the gallbladder.
Other Imaging Findings
- Cholescintigraphy which utilizes technetium-labeled hepatic 2,6-dimethyl-iminodiacetic acid (HIDA) may be helpful in the diagnosis of acute cholecystitis.
- Findings on a cholescintigraphy diagnostic of acute cholecystitis include:
- No visualization of the gallbladder
-
- Superior sensitivity to ultrasound
(see Fig. 3B). The main advantage of HIDA is its superior sensitivity in diagnosing acute cholecystitis. However, there are several disadvantages. Compared with US, cholescintigraphy is more expensive, time intensive (it takes several hours compared with 10–15 minutes for US), requires skilled staff, and is often not available after hours. It also exposes patients to ionizing radiation and provides information limited to the hepatobiliary system, whereas US and MRI do not expose patients to radiation and can provide added information outside the hepatobiliary system.
