摘　　要：目的探究CT及MRI在肠道克罗恩病诊断中的应用价值。方法回顾性分析2013年5月至2015年2月收治的30例小肠克罗恩病患者的临床资料,30例患者分别行CT和MRI检查,并经病理证实为小肠克罗恩病。分析CT和MRI表现特点,并进行总结。结果 30例患者CT检查共显示83节段肠壁炎性不均匀增厚,肠壁厚度6～15 mm,肠腔狭窄、肠壁强化25例,包括分层状强化6例,均匀强化19例;肠壁溃疡8例;肠系膜密度增高5例;肠系膜血管增多1例,扩张4例,扭曲5例;肠系膜淋巴结肿大11例;网膜内脂肪密度增高7例;肠间距扩大2例;＂木梳征＂6例。MRI检查结果显示30例患者共发现肠管病变119段,表现为信号升高或不均匀,形态固定,肠壁增厚,肠管狭窄或扩张,肠系膜血管毛刷征,系膜信号增高等。结论 CT和MRI检查可以很好地显示肠道克罗恩病的肠壁增厚分层、肠腔狭窄、肠系膜受累以及肠外并发症等,可较好的诊断及判断病情。Objective To investigate the application value of CT and MRI in the diagnosis of Crohn＇s disease.Methods From 2013 May to February 2015,the clinical data of 30 patients with small intestinal Crohn ＇s disease were retrospectively analyzed. Thirty patients underwent CT and MRI examination,they were pathologically diagnosed as small intestinal Crohn＇s disease. The CT and MRI features were analyzed and summarized. Results A total of 30 cases of CT examination showed that the 83 segment of the intestinal wall was not evenly inflammatory thickening,thickness 6 to 15 mm,intestinal luminal stenosis,intestinal wall enhancement in 25 cases,including hierarchical like enhancement in 6 cases,homogeneous enhancement in 19 cases; intestinal wall ulcer in 8 cases; mesenteric density increased in 5 cases; mesenteric vessels increased in 1case,dilatation in 4 cases,distortion in 5 cases; mesenteric lymph node enlargement in 11 cases; omentum fat density increased in 7 cases; intestinal space to expand in 2 cases; comb sign in 6 cases. MRI showed intestinal lesions were found with 119 section in 30 cases,the performance for the signal rise or uneven,form a fixed,thickening of intestinal wall and intestinal stenosis or expansion,mesenteric brush syndrome,mesangial signal increased,etc. Conclusion CT and MRI examination can well display the intestinal Crohn＇s disease of the bowel wall thickening and luminal stenosis,layered mesenteric involvement and parenteral complications,and can better diagnosis and judge the disease.
