Acute Cholecystitis Risk (Ultrasound + Clinical)

Patel et al. 2026 risk algorithm (with TG18/WSES context)

Risk-stratifies the probability of acute cholecystitis on gallbladder ultrasound using the data-derived algorithm of Patel et al. (2026): gallbladder distention, wall, contents, pericholecystic collections, hepatic artery PSV, sonographic Murphy sign, demographics and WBC are combined into practically excluded / reduced / elevated / substantially elevated risk, with approximate probability bands.

Also searched as: gallbladder · hepatobiliary · emergency · murphy

Patient sex (as listed in EMR)

GB contents

Pericholecystic irregular collection

Hepatic artery peak systolic velocity

Another reasonable cause for symptoms identified by imaging?

Another imaging observation substantially increasing concern for cholecystitis?
