Cholescintigraphy may be helpful in the diagnosis of acute cholecystitis. Cholescintigraphy is an alternative method of imaging and uses technetium-labeled hepatic 2,6-dimethyl-iminodiacetic acid (HIDA) in difficult cases or uncertain diagnosis. Findings on a cholescintigraphy diagnostic of acute cholecystitis include lack of visualization of the gallbladder.

Overview

Cholescintigraphy is the gold standard for the diagnosis of acute cholecystitis. Cholescintigraphy is an alternative method of imaging and uses technetium-labeled hepatic 2,6-dimethyl-iminodiacetic acid (HIDA) in difficult cases or uncertain diagnosis. Findings on a cholescintigraphy diagnostic of acute cholecystitis include lack of visualization of the gallbladder.
