多层螺旋CT多平面重建对机械性肠梗阻的诊断价值

The Diagnostic Value of Multiplanar Reconstruction Imaging with MSCT in Mechanical Intestinal Obstruction

目的:探讨多层螺旋CT(MSCT)多平面重建(MRP)对机械性肠梗阻的诊断价值。方法:收集65例经手术证实的机械性肠梗阻患者的MSCT资料,其中43例行MSCT平扫,22例行MSCT平扫加增强扫描。采用多平面重建技术对MSCT原始数据进行图像重建,并分析其表现。结果:对照手术病理,65例机械性肠梗阻中:肠粘连(25例),肠肿瘤(24例),肠扭转(5例),肠粪石(5例),肠套叠(4例),小肠克罗恩病(2例),MSCT多平面重建诊断机械性肠梗阻的准确率为100%,病因诊断准确率为84.6%。结论:MSCT多平面重建能清晰地显示机械性肠梗阻病变,有助于提高MSCT对机械性肠梗阻的病因诊断能力。

Objective： To evaluate the diagnostic value of multiplanar reconstruction （MPR） with Multi-slice spiral CT（MSCT） in mechanical intestinal obstruction. Methods：The MSCT datas of 65 mechanical intestinal obstructions confirmed by operation and pathology, were collected and reconstructed with multiplanar reconstruction technique,including 43 cases underwent plain scan ; the remaining 22 cases underwent plain and contrast-enhanced scan. Results： Contrast to operation and pathology,there were 25 adhesions,24 neoplasms,5 bowel torsions,5 bezoarhs, 4 intassusccptions,2 Crohn＇s diseases in 65 mechanical intestinal obstructions,the diagnostic accuracy of MPR in mechanical intestinal obstruction was 100% ,and the accuracy of the pathogeny was 84.6%. Conclusion： MPR with MSCT can clearly reveal mechanical intestinal obstruction,and help improve the ability of pathogeny diagnose in mechanical intestinal obstruetion.
