【摘要】 目的探讨64层螺旋CT三维重组在绞窄性和单纯性肠梗阻中的临床应用价值。资料与方法对37例肠梗阻患者,均进行了64层螺旋CT冠状位、矢状位最大密度投影(MIP)和容积再现(VR)等三维重组。结果64层螺旋CT显示肠梗阻的准确率为100%。绞窄性肠梗阻12例,包括肠扭转6例,肠系膜上静脉血栓形成3例,腹股沟疝3例。15例为肿瘤引起的单纯性肠梗阻。10例为肠粘连引起的单纯性肠梗阻(经保守治疗后好转出院)。结论64层螺旋CT三维重组对肠梗阻的诊断具有相当的优越性,在绞窄性和单纯性肠梗阻的原因、梗阻部位及梗阻程度的诊断方面有重要作用,可作为肠梗阻的首选检查方法。更多还原

【Abstract】 Objective To evaluate clinical value of 64-slice spiral CT three-dimensional reconstruction in the strangulation and simple intestinal obstruction.Materials and Methods 37 patients with intestinal obstruction were scanned by 64-slice CT.The original data were reconstructed by coronal,sagittal,maximum intensity projection(MIP)volume rendering(VR),and other three-dimensional reconstruction.Results 100% of cases with intestinal obstruction were detected by 64-slice spiral CT.12 patients were diagnosed strangulation intestinal obstruction,Including 6 cases of volvulus,3 cases of superior mesenteric vein throm-bosis,3 cases of inguinal hernia.15 cases were simple intestinal obstruction caused by tumors,and 10 cases were caused by intestinal adhesion(the patients feel better after conservative treatment).Conclusion Three-dimensional reconstruction of 64-slice spiral CT,wihch give the important information including the cause,the degree and the site of obstruction,has superiority in diagnosing the strangulation and simple intestinal obstruction and should be regarded as the first choice for intestinal obstruction.更多还原
