肠梗阻的64排螺旋CT诊断

APPLICATION OF SIXTY-FOUR SLICE SPIRAL CT ON DIAGNOSIS OF MECHANICAL INTESTINAL OBSTRUCTION

目的探讨64排螺旋CT(64-MSCT)在机械性肠梗阻中的诊断价值及优势。方法回顾性分析总结82例临床有肠梗阻症状病例64-MSCT表现。扫描采用64-MSCT平扫或增强扫描,成像方式为薄层横断面、多方位、多方法重建。结果诊断肠梗阻的准确率为90.6%。手术病例结果与64-MSCT表现相符。主要包括大肠肿瘤,肠粘连性梗阻等。结论 64-MSCT对机械性肠梗阻的程度、部位和梗阻病因的诊断及提示肠缺血有重要价值,可作为肠梗阻的首选检查方法。

Objective To investigate the value and advantages of Sixty- four slice spiral CT （64- SCT） in the diagnosis of mechanical bowel obstruction. Methods 64- slice CT and surgical findings in 82 cases of mechanical intestinal obstruction were retrospectively analyzed. All cases were scanned using 64 - SCT noncontrast or contrast enhancement, and the thin slice axial image and MPR image were also analyzed. Results 64 - SCT diagnostic accuracy of intestinal obstruction was 90.6~. CT manifestation and patho- logical findings were consistent, including neoplasm, adhesions, etc. Conclusion 64 - SCT can identify the site, level and the causes of obstruction, and show the ischemia of intestine. It may be the first choice in diagnosis of acute bowel obstruction.
