Q

What is the first-line imaging modality for suspected acute cholecystitis?

A

Abdominal Ultrasound

Transabdominal gallbladder US is best test to detect gallstones and evaluate GB disease
* Ultrasonographic Murphy sign: local abdominal tenderness over GB
* Pericholecystic fluid and GB wall thickening indicates acute inflammation

Classically CT scans are done in the ED, but they are not first-line nor the best test in diagnosing acute cholecystitis

Q

Why is a transabdominal ultrasound superior to CT scans in diagnosing acute cholecystitis?

A
  • Visualization of Gallbladder Wall and Structures: US is superior when visualizing the GB and detecting its thickening, which is a key indicator of acute cholecystitis
  • Reproduction of Murphy’s Sign
  • Non-invasive and is a quick test in the ED
