摘要

In this prospective study, Magnetic Resonance Cholangiography (MRC) and Intra-Operative Cholangiography (IOC) were compared for the diagnosis of suspected CBD stones. Thirty patients with gall stones and suspected CBD lithiasis (abnormal serum liver tests and CBD size>7 mm on ultrasound) had MRC followed by open cholecystectomy and IOC. All MR imaging was done using a 1.5-T whole body scanner (Signa, General Electric Medical Systems). A torso phased-array coil with a 4-channel receiver was used for data acquisition. Over a period of 18 months, 30 patients (average age, 53.93 ± 13.3 years; range, 38-76 years) were enrolled in this study. There were 11 males (36.7%) and 19 females (63.3%). On MRC, CBD stones were diagnosed in 19 patients, while on IOC, CBD stones were diagnosed in 22 patients. In the present study, the sensitivity of MRC for diagnosing CBD stones was 81.8%, the specificity was 87.5%, the positive predictive value was 94.7% and the negative predictive value was 63.3%. Pre-operative MRC may obviate the need for intra-operative cholangiography. MRC reduces operating time, is less invasive and may also reduce damage to the CBD that can occur during IOC. MRC can identify CBD stones pre-operatively and can help surgeons plan safe procedures. Pre-operative MRC should be done routinely in patients whose clinical or biochemical findings suggest the possibility of CBD stones.
