Overview

Cholescintigraphy is the gold standard for the diagnosis of chronic cholecystitis. Transabdominal ultrasonography is the initial study of choice for the diagnosis of chronic cholecystitis and gallstones.
The following result of transabdominal ultrasonography is confirmatory of chronic cholecystitis:
- Thickened gallbladder (>4 mm)
- Gallstones
The ultrasound should be performed when:
- The patient presents with right upper quadrant pain, abdominal guarding, fever, and a positive Murphy's sign.
