Overview
HIDA cholescintigraphy is the most sensitive and accurate modality for the diagnosis of chronic cholecystitis. HIDA cholescintigraphy findings for chronic cholecystitis include delayed gallbladder isotope accumulation, irregular gallbladder filling, or photopenic areas and septations.
Other Imaging Findings
Cholescintigraphy
HIDA cholescintigraphy findings for chronic cholecystitis include delayed gallbladder isotope accumulation, irregular gallbladder filling, or photopenic areas and septations. A gallbladder ejection fraction of less than 35% after the administration of cholecystokinin indicates the presence of the chronic calculus or chronic acalculous cholecystitis.
- Hepatobiliary scintigraphy with technetium-99m is also sensitive and accurate for diagnosis of chronic cholecystitis. It can also assess the ability of the gallbladder to expel bile (gallbladder ejection fraction), and a low gallbladder ejection fraction has been linked to chronic cholecystitis. However, since most patients with right upper quadrant pain do not have cholecystitis, primary evaluation is usually accomplished with a modality that can diagnose other causes as well. [1] [2]
- Signs of chronic cholecystitis on HIDA cholescintigraphy include delayed gallbladder isotope accumulation, irregular gallbladder filling, and septations. A gallbladder ejection fraction of less than 35% after the administration of cholecystokinin indicates the presence of chronic calculus or chronic acalculous cholecystitis.[3]
Acalculous Cholecystitis
The HIDA cholescintigraphy based diagnostic criteria from multiple studies for acalculous cholecystits is as follows.[4]
| Criteria | Diagnosis |
|---|---|
| RC MC |
Nonvisualization of the gallbladder 1 hour after injection of radiolabeled technetium ([this is radionuclide cholescintigraphy (RC)] Nonvisualization of the gallbladder 30 minutes after injection of morphine (after initial radiolabeled technetium) [this is morphine cholescintigraphy (MC)] |
Diagnosis: RC alone or RC and MC.
