Patients with common bile duct (CBD) stone disease suffer from the relatively long scan time of magnetic resonance cholangiopancreatography (MRCP). Compressed sensing (CS) is a technique that can accelerate the speed of MRI and has been applied to MRCP. This study investigated the utility of CS-MRCP in diagnosing CBD stone disease in comparison with conventional MRCP on the 1.5T scanner. The results showed that CS-MRCP could provide comparable image quality with conventional MRCP for the diagnosis of CBD stone disease but with a substantially shorter acquisition time (1:35 vs. 4:08 mins).
