MSCT后处理技术在肿瘤性肠梗阻诊断中的价值

目的 探讨MSCT后处理技术诊断肿瘤性肠梗阻的价值。方法 分析41例经手术、病理证实的肿瘤性肠梗阻术前及MSCT后处理的影像表现，与临床手术和病理结果进行对照研究。结果 MSCT对本研究中肿瘤性肠梗阻的诊断准确率100％，对肿瘤定位诊断准确率为100％（41／41），定性诊断准确率为97．6％（40／41）。STS-MIP后处理技术可以显示29例（29／41，70．7％）肿瘤的供血动脉及引流静脉。结论 MSCT是术前无创性诊断肿瘤性肠梗阻的重要方法，对引起梗阻的肿瘤的定位、定性准确性高，对肿瘤的供血血管能较好显示，具有重要的临床意义。

Value of MSCT Post-processing Techniques in the Diagnosis of Tumorous Ileus

Objective To evaluate the role of MSCT(Multi-Slices helical CT) and its post-processing techniques in diagnosis of neoplastic intestinal obstruction.Methods Clinical data of 41 cases of tumorous ileus-revealed by plane and contrast-enhanced MSCT manifestations and MPR(Multi-Planar Reconstruction),STS-MIP(Sleek Thin Slice-Maximum Intensity projection) and other post-processing techniques were analyzed and compared with the results of surgical findings and pathology.Results 1.The accuracy of orientation and determination of the nature of intestinal obstruction by neoplasm was 100% and 97.6%,respectively.2.The 70.7% feeding arteries and draining vein can be revealed by post-processing techniques like STS-MIP.Conclusion MSCT and its MPR,STS-MIP and other post-processing techniques have an important clinical value in orientation and determination of the nature of neoplastic intestinal obstruction.
