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 explore the value of CT and MRI in the diagnosis of intestinal Crohn’s disease. Methods The clinical data of 30 patients with small bowel Crohn’s disease admitted from May 2013 to February 2015 were analyzed retrospectively. Thirty patients were examined by CT and MRI, and pathologically confirmed as Crohn’s disease of the small intestine. Analysis of CT and MRI performance characteristics, and to summarize. Results CT examination of 30 patients showed 83 segments of non-uniform inflammatory thickening of the intestinal wall, intestinal wall thickness of 6 ~ 15 mm, narrow intestine, intestinal wall enhancement in 25 cases, including stratified enhancement in 6 cases, uniform enhancement in 19 cases ; Intestinal ulcer in 8 cases; increased mesenteric density in 5 cases; mesenteric vascular increased in 1 case, dilated in 4 cases, distorted in 5 cases; mesenteric lymph node enlargement in 11 cases; increased omentum fat density in 7 cases; “Mu comb sign ” 6 cases. The results of MRI showed that 119 cases of intestinal lesions were found in 30 patients. The symptoms were ascending or non-uniform signal, fixed shape, thickening of the intestinal wall, stenosis or dilation of the intestine, brushing of mesenteric vessels and increased mesangial signal. Conclusion CT and MRI can be a good indicator of bowel Crohn’s disease intestinal wall thickening stratification, intestinal stenosis, mesenteric involvement and extraintestinal complications, can be a better diagnosis and judgment of the disease.
