| 目的 探讨磁共振胰胆管造影结合多种MRI技术对胰胆管疾病诊断的价值。方法 对经手术病理或ERCP证实的胰胆管疾病患者100例,行包括冠状位T2加权、横断位T2加权、横断位T1加权、Turbo SE MRCP序列及HASTE MRCP序列的MRI检查。结果 MRCP对胰胆管疾病定性诊断准确率为91.0%;结合其他MR成像序列,定性诊断准确率为99.0%(χ2=6.7368, P<0.05)。对胆系结石,Turbo SE MRCP检出率为94.9％,HASTE MRCP原始图像结合3D图像的检出率为98.7％;HASTE MRCP 3D图像检出率为84.6％,与Turbo SE MRCP之间存在显著差异(χ2=4.4572, P<0.05)。结论 MRCP与其他MR成像技术结合应用,可准确判断梗阻部位,明确病变性质。 |

| Objective To investigate the value of magnetic resonance cholangiopancreatography (MRCP) combined with varied magnetic resonance imaging (MRI) techniques in diagnosis of pancreaticobiliary tract disease. Methods One hundred patients with pancreaticobiliary tract diseases confirmed with pathology or endoscopic retrograde cholangiopancreatography (ERCP) were enrolled in this study. All patients were examined by five MRI sequences, including T2-True FISP, T2-HASTE, T1-FLASH, Turbo SE MRCP (thick slice), and HASTE-MRCP (thin slice). Results For pancreaticobiliary tract diseases, the qualitative diagnostic accuracy was 99.0% using MRCP and other three MRI sequences, but 91.0% with only MRCP (χ2=6.7368, P<0.05). For biliary stones, the detectable rates of turbo SE MRCP and HASTE-MRCP combined with 3D reconstructed images were 94.9% and 98.7%, respectively, significantly different from with only 3D reconstructed images (84.6%, χ2=4.4572, P<0.05). Conclusion MRCP combined with other MRI techniques can accurately display the location and nature of pancreaticobiliary tract diseases. |
