64排螺旋CT多平面重建对急性肠梗阻的诊断价值

Diagnostic Value of 64-slice Spiral CT Multi-planar Reconstruction for Acute Intestinal Obstruction

目的探讨64排螺旋CT薄层扫描多平面重建(multi-planar reconstruction,MPR)对急性肠梗阻的诊断价值。方法对60例经手术病理证实为急性肠梗阻的患者CT诊断资料作回顾性分析,对图像进行整理、分析和重建。采用动态形式连续显示横断面图像,追踪患者肠管走行,确定梗阻位置,最后重建横断面图像以获取不同角度MPR图像。结果梗阻发生部位:小肠35例(58.3%),结肠25例(41.7%);梗阻发生原因:单纯性肠梗阻46例(76.7%),绞窄性肠梗阻14例(23.3%)。64排螺旋CT与临床手术病理诊断结果相符,诊断准确率为100%。结论 64排螺旋CT薄层扫描MPR技术能清晰显示急性肠梗阻病灶部位,提高了确定病因及病灶范围的诊断能力。

Objective To investigate the value of 64-slice spiral CT multi-planar reconstruction （MPR） for the diagnosis of acute intestinal obstruction. Methods CT data of 60 patients with pathologically con{irmed acute intestinal obstruction were retrospectively analyzed. The images were collated,analyzed and reconstructed. Dynamic form o{ cross-sectional images were used for tracking intestinal tracts, determining the location of obstruction, and finally reconstructing cross- sectional images to obtain different angles of MPR images. Results Among the 60 patients, 35 （58.3%） had small intestinal obstruction and 25 （41.7%） had colon obstruction. The causes of obstruction included simple obstruction （46 cases,76.7%） and strangulated obstruction （14 ca- ses, 23.3 % ）. The operative outcome was consistent with the 64-slice spiral CT. The diagnostic ac- curacy was 100%. Conclusion The 64-slice spiral CT combined with MPR scanning technology can clearly show the lesion site and improve diagnostic capabilities of determining the causes and lesion range in patients with acute intestinal obstruction.
