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.
