摘要
目的:探讨64层螺旋CT在肠道急腹症病因诊断中价值。方法:对46例经手术或临床证实的肠道急腹症病例资料行64层螺旋CT平扫加增强扫描,并进行回顾性分析。主要重组方法为多平面重组(MPR)、最大密度投影(MIP)及容积再现(VR)。结果:46例病例中,肠道肿瘤22例、肠道炎性病变11例、憩室5例、淋巴瘤2例、肠系膜上静脉血栓1例、肠坏死1例、麻痹性肠梗阻伴全内脏转位1例、单纯性肠扭转1例、腹壁疝及闭孔疝各1例;其中64层螺旋CT准确诊断(定位定性)40例,诊断符合率87.0%,4例结肠癌误诊为炎性病变,漏诊脂肪瘤及肠穿孔各1例。结论:64层螺旋CT扫描及重组图像对肠道病变显示直观、准确,对肠道急腹症的病因诊断具有重要的诊断价值。
Objective:To assess the value of 64-slice spiral CT in the cause diagnosis of intestinal tract acute abdomen.Methods:Forty-six patients with intestinal tract acute abdomen were examined using unenhanced CT and contrast-enhanced CT scans.CT findings were correlated with pathological and follow-up results in order to evaluate the accuracy of CT in the diagnosis of intestinal tract acute abdomen.The major methods of reconstruction were MPR,MIP and VR.Results:The results of CT and surgical findings were consistent in 40 (87.0%) of 46 cases with intestinal tract acute abdomen,including neoplasm 22 cases,inflammation 11 cases,diverticulum 5 cases,lymphoma 2 cases,superior mesenteric vein thrombosis 1 case,intestinal necrosis 1 case,paralytic ileus with transposition of the entire visceral 1 case,simple volvulus 1 case,abdominal wall hernia 1 case and obturator henia 1 case.Four cases of colon cancer were misdiagnosed as inflammatory lesions.Lipoma and intestinal perforation were missed for one case each.Conclusion:Three-dimensional reformated images of 64-slice spiral CT can clearly and correctly demonstrate the lesions of intestinal tract.It is valuable in the cause diagnosis of intestinal tract acute abdomen.
