摘　　要：目的：探讨多层螺旋CT小肠造影（MSCTE）对小肠病变的诊断价值。方法：对36例疑有小肠病变的患者行螺旋CT平扫及增强检查。检查前清洁肠道,肌注盐酸654-210~20mg以减少肠蠕动,口服足量等渗甘露醇水对比剂充盈肠管,结合多平面重组（MPR）或最大密度投影（MIP）观察。结果：经病理证实,病变组共20例：小肠肿瘤14例,其中腺癌4例,间质瘤6例,淋巴瘤2例,腺瘤和类癌各1例;Crohn’s病3例;术后粘连性肠梗阻3例。余为正常组。结论：多层螺旋CT小肠造影双期增强扫描结合重建技术对小肠病变的定位、定性及肿瘤分期有较高临床价值。Objective： To investigate the value of multi-slice CT enterography （MSCTE） in intestinal diseases. Methods： Helical CT scans were perfomed in 36 patients before and after infusion of contrast medium. Before CT examination, all patients were injeeted 10-20mg 654-2 to minimize bowel movement then took administered iso-osmotie mannitol to fill the bowl. Multiplanar reformation（MPR）, maximum intensity projection（MIP） were carried out. Results： Among 14 cases of intestinal neoplasms, there were 4 eases of adenoeareinoma, 6 cases of stromal tumor, 2 cases of lymphoma, 1 case of adenoma and 1 ease of eareinoid tumor, 3 eases of Crohn＇s diseases, and 3 eases of postoperative adhesion. The others were normal. Conclusion： MSCTE using biphasie enhaneing and 3D-image reeonstruetion teehniques was valuable for intestinal diseases.
