【摘要】 目的探讨粘连性肠梗阻的多层螺旋CT成像特征。方法7例手术证实为粘连性肠梗阻患者,术前均行全腹多层螺旋CT扫描,并以手术及病理结果为标准,评价多层螺旋CT成像特征及图像后处理MPR的应用价值。结果7例粘连性肠梗阻患者,其中23例非癌性粘连,螺旋CT清楚显示梗阻近端肠管扩张,梗阻移行处肠管塌陷或锯齿鸟嘴状,移行带光滑,未见明确器质性病变;5例癌性粘连,清楚显示梗阻移行处或周围网膜、系膜有大小不等结节灶,而2例术后证实为癌性粘连CT不能作出癌性诊断;7例绞窄性肠梗阻显示肠壁增厚,密度减低或增高,肠壁增强明显减弱或无强化,肠壁积气,肠系膜水肿或血管增粗,腹水等特征性影像。结论多层螺旋CT对诊断粘连性肠梗阻具有重要的临床应用价值。更多还原

【Abstract】 Objective To discuss adhesive ileus features of multi-slice spiral CT imaging. Methods Confirmed 37 cases of surgery for patients with adhesive ileus,underwent preoperative abdominal-wide multi-slice spiral CT scan,and the results of surgery and pathology as the standard to evaluate the characteristics of multi-slice spiral CT imaging and image post-processing of the application of the value of MPR. Results 37 cases of patients with adhesive ileus,among them ,23 cases of non-cancerous adhesions,obstruction of spiral CT clearly shows the expansion of the proximal intestine,ileus transitional department collapse or serrated beak-shaped,smooth transitional zone,no clear pathological changes; 5 cases of cancer of adhesion,clearly shows obstruction transitional department or around the omentum,mesangial nodular lesions ranging in size,while 2 cases after the operation confirmed adhesion CT diagnosis of cancer can not be made; 7 cases of strangulating ileus shows the bowel wall thickening,density increased or reduced ,bowel enhanced significantly weakened or no enhancement,pneumatosis intestinalis,mesenteric edema or vascular thickening,ascites and other features of images. Conclusion Multi-slice spiral CT has an important clinical value in the diagnosis of adhesive ileus.更多还原
