目的：探讨磁共振（MR）胰胆管造影对胰腺分裂的诊断价值。材料和方法：在310例患者中，采用重t2加权、二维、快速自旋回波序列进行MR成像。139例患者使用了体线圈，171例患者使用了躯干多线圈和高分辨率成像参数。108例患者与内窥镜逆行胰胆管造影（ERCP）相关。结果：268例（86%）诊断。268例患者中有25例（9%）磁共振成像发现胰腺分裂（观察者间一致性为98% [kappa = .881]）。在171例躯干多线圈检查中，10%无法诊断，胰腺分裂的检出率为12%。108例接受ERCP的患者中有6例出现胰腺分裂，这些患者的MR成像结果没有假阴性或假阳性。结论：MR胰胆管造影是诊断胰腺分裂的准确工具，可替代ERCP。
PURPOSE: To determine the usefulness of magnetic resonance (MR) cholangiopancreatography in the diagnosis of pancreas divisum.MATERIALS AND METHODS: In 310 patients, MR imaging was performed with heavily T2-weighted, two-dimensional, fast-spin-echo sequences. A body coil was used for 139 patients, and a torso multicoil and high-resolution imaging parameters were used for 171 patients. In 108 patients, correlation with endoscopic retrograde cholangiopancreatography (ERCP) was available.RESULTS: Two hundred sixty-eight examinations (86%) were diagnostic. Pancreas divisum was observed with MR imaging in 25 of 268 cases (9%) (interobserver agreement, 98% [kappa = .881]). Among the 171 examinations performed with a torso multicoil, 10% were nondiagnostic and the rate of detection of pancreas divisum was 12%. Pancreas divisum was depicted in six of the 108 patients who underwent ERCP, and there were no false-negative or false-positive MR imaging results in these patients.CONCLUSION: MR cholangiopancreatography is an accurate tool in the diagnosis of pancreas divisum and could replace ERCP.
