| 目的 比较64排螺旋CT胰胆管三维成像与MR胆胰管成像(MRCP)对胰胆管梗阻性疾病的诊断价值。方法 对胰胆管梗阻性疾病患者36例行常规腹部增强CT及MRCP检查,将CT门静脉期图像分薄至层厚0.625 mm后,对肝内外胆管、胆囊及胰腺进行多平面重建(MPR),必要时加做曲面重建(CPR)。根据手术病理或内镜检查结果,比较MPR(和CPR)与MRCP对病变的定位、定性诊断符合率。结果 MPR与MRCP对病变定位诊断的符合率分别为97.22%、94.44%;定性诊断符合率MPR为83.33%,部分病例加做CPR后提高至88.89%,MRCP定性诊断符合率为80.56%。两者定位、定性诊断符合率差异无统计学意义,诊断符合率一致性中等(Kappa=0.471)。结论 MSCT胰胆管三维成像与MRCP都具有很高的诊断价值,而MSCT胰胆管成像更利于临床解读。 |

| Objective To compare the diagnostic value of 64-slice helical CT cholangiography and MR cholangiopancreatography (MRCP) for pancreaticobiliary obstructive diseases. Methods Thirty-six patients with pathologically proved pancreaticobiliary obstruction or endoscopic retrograde cholangiopancreatography (ERCP) were examined with MRCP and routine enhanced CT scanning. CT row data of portal venous phase were reconstructed with 0.625 mm thickness and intervals. Then multiplanar reformation (MPR) of intra- and extrahepatic biliary duct, gallbladder and pancreas was generated, and curved planar reformation (CPR) was performed when necessary. The accuracy of MPR (and CPR) and MRCP in evaluating the site and nature of obstruction was compared. Results The accuracy of MPR and MRCP was 97.22% and 94.44% in evaluating the site of obstruction, respectively. In evaluating the nature of obstruction, the accuracy of MPR and MPCP was 83.33% and 80.56%, respectively, and the accuracy of MPR increased to 88.89% in combination with CPR in some patients. There was no statistical difference between the accuracy of MPR and MRCP in evaluating the site and nature of obstruction, while their diagnostic consistency was medium (Kappa=0.471). Conclusion Both MSCT cholangiography and MRCP have high diagnostic value in pancreaticobiliary obstruction, while the former gets some advantages in images review for clinicians. |
