摘要
目的:探讨64排螺旋CT增强扫描胰胆管曲面成像对胆道梗阻性疾病的临床诊断价值。方法:前瞻性收集81例临床诊断为梗阻性黄疸的病人,行64排螺旋CT腹部增强扫描检查,同时行MRCP、MRI检查,所有病例均行手术或ERCP检查获得病理结果。利用曲面重建技术对所得CT增强图像进行胰胆管曲面重建,与MRCP、MRI检查结果对比,并与手术病理结果对照。结果:对于胆道梗阻:在定位诊断方面,64排螺旋CT增强扫描胰胆管曲面成像与MRCP+MRI无明显差异;在定性诊断方面,对于良性病变尤其是对结石的诊断,前者高于后者。结论:应用64排螺旋CT增强扫描胰胆管曲面成像对于胆道梗阻性疾病具有重要诊断价值。
Objective： To evaluate the efficiency of imaging diagnosis of obstruction of bile duct by cholangiopancreatic curved reformatted image using 64-slice spiral CT. Methods： Eighty-one cases with obstruction of bile duct received 64-slice contrast-enhanced spiral CT scanning and MRI, MRCP at the same time. All cases had pathology by operation or ERCP. All patients were reconstructed through curved reformatted （CR） technique and oblique anteroposterior axial location of multiplanar reconstruction, and compared with MRCP, MRI, meanwhile also compared with operative pathology. Results： There are no obvious difference for position identifying of obstruction of bile duct between cholangiopancreatic curved reformatted image using 64-slice spiral CT and MRCP＋MRI, the diagnosis in qualitation of obstruction, especially in diagnosing obstruction caused by gallstone, the former is better than the latter. Conclusion： Using the cholangiopancreatic curved reformatted method of 64 slice spiral CT has very important value in the diagnosis of obstruction of bile duct.
