Fig. 2.

A 72-year-old man with severe right upper quadrant pain for one day and abnormal liver function tests. Axial HASTE (A, arrow) and axial T2-fat saturated (B, arrow) sequences show a gallstone in the distal common bile duct with dilatation of the bile duct, as correctly interpreted by both readers using the abbreviated image set. Both readers assigned the MRCP, including MRCP PACE (C), with a low quality score of 2, indicating minimal information provided as the images depicted a dilated common bile duct but otherwise poor visualization of the biliary tree secondary to breathing motion
