【摘要】 目的:探讨多层螺旋CT(MSCT)低张小肠造影扫描技术在小肠疾病诊断中的临床应用价值。方法:对内镜诊断或怀疑小肠疾病患者40例行低张+MSCT扫描,以横断面为主,结合多平面重组(MPR)及最大密度投影(MIP)观察病变部位、大小、形态、周围侵犯及转移情况,结果与内镜活检或术后病理对照分析。结果:40例中,小肠癌15例,其中1例因病变范围较小而漏诊,其T、N、M分期准确性分别为94.5%、90.5及96.5%;淋巴瘤6例;小肠Crohn病9例,小肠间质瘤4例,小肠血管瘤1例,小肠结核1例,肠系膜上动脉血栓1例,阴性3例。结论:MSCT低张小肠造影技术操作简便、易行,患者耐受性良好,能显示肠镜不能通过的狭窄段。MPR、MIP后重建对于小肠疾病的术前定位、定性以及鉴别诊断具有较高的临床应用价值。更多还原

【Abstract】 Objective:To evaluate the application value of multi-slice spiral CT(MSCT) and hypotonic technique in small intestine diseases.Methods:40 patients with endoscopic diagnosis or suspected small intestine disease had underwent hypotonic and MSCT scanning.The location,size,shape,surrounding invasion and metastasis of the colon lesions were analyzed in cross-section images,combined with multi-planar reformation(MPR),maxiumum intensity procedure(MIP) images.The tumor TNM staging was evaluated with endoscopic biopsy or operation pathology.Results:There were small intestine cancer(n=15),lymphoma(n=6),Crohn disease(n=9),small intestinal stromal tumor(n=4),small intestine angioma(n=1),tuberculosis of small intestine(n=1),mesenteric artery thrombosis(n=1) negative(n=3) in 40 patients.The T,N,M staging accuracy of colon cancer was 94.5%,90.5% and 96.5% respectively.one case of small intestine cancer was due to a smaller range and missed lesions.Conclusion:MSCT scanning technique with hypotonic for small intestine disease is well tolerated by patients.It can show the narrow segment that colonscopy can not pass through.MPR and MIP is very valuable to pre-operation position in patients with small intestine diseases and differentiated diagnosis.更多还原
