Magnetic resonance imaging (MRI) and magnetic resonance cholangiopancreatography (MRCP) in a patient with acute cholecystitis

MRI and MRCP images from a patient with acute cholecystitis. Contrast enhanced (A) and fat saturated T2-weighted imaging (B) reveal a hyperemic gallbladder wall (arrowheads). Multiple small stones are noted lying dependently in the base of the gallbladder (arrow). The MRCP in the coronal projections (C and D) reveals accumulation of pericholecystic fluid (dashed arrows). These findings are consistent with the diagnosis of acute cholecystitis.
