Overview

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.

Other Imaging Findings

• Cholescintigraphy which utilizes technetium-labeled hepatic 2,6-dimethyl-iminodiacetic acid (HIDA) may be helpful in the diagnosis of acute cholecystitis. Cholescintigraphy is used in difficult cases or uncertain diagnosis.
• Findings on a cholescintigraphy diagnostic of acute cholecystitis include:
  • No visualization of the gallbladder
• Advantages of cholescintigraphy:
  • Superior sensitivity to ultrasound
• Limitations of cholescintigraphy:
  • Expensive
  • Takes several hours
  • Radiation exposure
  • Requires skilled staff
