摘　　要：目的探讨多层螺旋CT及其后处理技术在胆总管恶性梗阻性病因诊断中的应用价值。方法对38例梗阻性黄疸患者均行常规CT平扫及三期增强扫描,之后进行MPR、CPR、MIP及MinIP等重建,对病变作出病因诊断,结合病理结果进行评价。结果 38例胆总管梗阻患者病变定位定性诊断准确率分别为100%、94.7%(36/38);CT平扫横轴位图像显示病变能力与横轴位图像加重建图像相比无明显差异;三期增强扫描横轴位加重建图像显示病变能力明显高于增强扫描横轴位图像。结论多层螺旋CT及其后处理技术为胆总管恶性梗阻性病变的有效检查方法。Objective To investigate MSCT and post-processing techniques in the etiological diagnosis of common bile duct malig- nant obstruction. Methods 38 cases of patients with obstructive jaundice were all undergoing routine CT scan and three enhanced scan, and then make diagnosis of the cause of the lesion according to the reconstruction of the MPR, CPR, MIP and MinlP, combined with pathological evaluation of the results. Results The location qualitation and diagnostic accuracy of 38 patients with common bile duct obstruction lesion were 100% ,94. 7% （36/38） ;The detected lesions ability between CT scan axial images and axial images plus reconstruction image was no significant difference;the three enhanced scan axis plus the reconstructed images show lesions ability sig- nificantly higher than the enhanced scan axial images. Conclusion MSCT and post - processing techniques were an effective method for the malignant obstruction of the common bile duct.
