| 目的 评价多层螺旋CT(MSCT)阴性法胆管造影(N-CTCP)对胆管梗阻的诊断价值。方法 对60例怀疑有胆管梗阻的病例进行N-CTCP成像，使用曲面重建(CPR)和最小密度投影(Min-IP)技术对有无胆管梗阻、梗阻部位及梗阻病变的性质进行评价，并将其结果与手术和(或)病理结果对照。结果 60例均一次屏气完成扫描，N-CTCP成像显示胆管满意，CPR加Min-IP对胆管梗阻的定位诊断与定性诊断的灵敏度分别为89.86%、88.64%，特异度分别为94.59%、81.25%，阳性预测值分别为91.18%、92.86%，阴性预测值分别为93.75%、72.22%，阳性似然比分别为16.61、4.73，阴性似然比分别为0.11和0.14。结论 N-CTCP对胆管梗阻性疾病定位准确，对良性及恶性胆管梗阻判断有较高准确性。 |

| Objective To assess the value of negative MSCT cholangiography (N-CTCP) in diagnosis of bile duct obstruction. Methods Sixty patients suspected of bile duct obstruction underwent MSCT scan， and the images were reconstructed with curved planar reformation (CPR) and minimum intensity projection (Min-IP) in order to detect the location and define bile duct diseases. The imaging results of N-CTCP were compared with that of surgical operation and pathology. Results All patients were examined successfully to demonstrate bile ducts. The sensitivity (SE), specificity (SP), positive predictive value (PPV), negative predictive value (NPV), positive likelihood ratio (PLR) and negative likelihood ratio (NLR) were 89.86%, 94.59%, 91.18%, 93.75%, 16.61 and 0.11 of the location, whereas 88.64%， 81.25%， 92.86%, 72.22%， 4.73 and 0.14, respectively, of definition of obstruction of bile duct. Conclusion N-CTCP can accurately define the obstructive site， and is very useful in diagnosing bile duct obstructive diseases both the location and identification of the benign or malignant lesions. |
