经会阴前列腺穿刺活检在临床中的应用价值

目的：探讨8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45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：45例梗阻性黄疸中，胆管癌6例，胰腺癌10例，胆总管结石25例，胆总管炎性狭窄4例。CT结合MPR、CPR诊断准确率为85．6％，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。

The application and significance of multi--slice CT scanning combined with multi--planar recon struction and curved planar reformation in diagnosis of obstructive jaundice

Objective：To analyze the clinical application and significance of multi--slice CT scanning, multi--planar reconstruction （MPR） and curved planar reformations （CPR）in diagnosis of obstructive jaundice. Methods：Multi--slice CT scanning, MRP and CPR were performed in 27 patients with obstructive jaundice. These results were compared with those of operation and pathological ex- amination. Results： Among 27 patients with obstructive aundice,4 of them suffered with cholangiocarcinoma,6 with pancreatic carci- noma,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.
