Is a Negative CT Good Enough to Rule Out Acute Cholecystitis?
Computed tomography (CT) is an important modality that is commonly used to diagnose biliary pathology. It may be better than ultrasound for detecting acute cholecystitis but still misses cases found on cholescintigraphy. Thus, further imaging for cholecystitis should be considered in high-risk patients with a negative CT.
