摘　　要：目的探讨16层螺旋CT多平面重建(MPR)和曲面重建(CPR)在阻塞性黄疸诊断中的临床应用价值。方法对27例梗阻性黄疸病例行螺旋CT平扫,通过MPR及CPR技术对梗阻部位及性质进行诊断,并与手术、病理对照。结果27例梗阻性黄疸中,胆管癌4例,胰腺癌6例,胆总管结石15例,胆总管炎性狭窄2例。CT结合MPR、CPR诊断准确率为88.8%,良、恶性梗阻的鉴别诊断准确率为88.8%。结论多层螺旋CT平扫结合MPR和CPR图像后期处理技术,能准确显示胆道梗阻的部位和程度,直观地显示病变的范围及与周围组织的关系,对胆道系统梗阻病变的定位、定性具有很高的诊断价值。Objective To analyze the clinical application and significance of multislice CT scanning,multiplanar reconstruction（MPR） and curved planar reformations（CPR） in diagnosis of obstructive jaundice.Methods Multislice CT scanning,MRP and CPR were performed in 27 patients with obstructive jaundice.These results were compared with those of operation and pathological examination.Results Among 27 patients with obstructive jaundice,4 of them suffered with cholangiocarcinoma,6 with pancreatic carcinoma,15 with common duct stones and 2 with choledochitis stenosis.The accuracy of MPR and CPR on localizing diagnosis were both 88.8 %.The accuracy of differential diagnosis between benign and malignant obstruent diseases was 88.8 %.Conclusion MPR is equal to CPR in localizing diagnosis of obstructive jaundice.These 2 reconstruction techniques have respective predominance and limitation,they should be combined with each other in clinical diagnosis.
