目的探讨螺旋CT薄层重建技术在梗阻性黄疸的诊断价值,以提高对梗阻性黄疸临床诊断准确率.方法对30例经手术病理证实的梗阻性黄疸患者行螺旋CT螺旋扫描、平扫及增强扫描,层厚和间隔均为5 mm,然后对原始数据进行层厚为1 mm、间隔为1.5mm的薄层轴位重建,并传入工作站进行薄层多平面重组,对胆管梗阻定位和定性诊断作出评价.并与手术病理对照.结果螺旋CT薄层重建技术对梗阻性黄疸定位和定性的准确率分别为98%和93%.结论螺旋CT薄层重建技术对梗阻性黄疸定位和定性准确率高,是一种很好的无创性检查方法.

Objective To approach the value of spiral CT thin imaging reconstruction in the diagnosis of obstructive jaundice in order to improve the correctness of the diagnosis.Methods Analysis the cases'clinical manifestation and the CT images,who were diagnosed as obstructive jaundice by operation.All of cases had high-resolution computed tomograyhy scan.The thickness and the interval is 5mm,reconstructed the thickness and the interval to 1mm and 1.5 mm,then send the images to the workstation and MRR were processed.Analysis the date with the pathology.Results Spiral CT thin imaging reconstruction have 98% and 93% in the accuracy of location and characterization in the obstruction.Conclusion The spiral CT thin imaging reconstruction is a good method to improve the accuracy of location and characterization in the obstructive jaundice.
