摘　　要：目的:分析磁共振肠道检查在肠道病变中的表现,评估3T磁共振超快速高分辨率VIBE序列在肠道病变诊断中的应用价值。方法:2015年1月-2017年9月经临床诊断为肠道病变的患者37例,行常规MR的T1WI、T2WI、DWI和3D Vibe冠状位多期动态增强扫描,对所获得的图像资料主要分析病灶所在部位、病变强化特点、肠壁厚度、肠管内径及周围组织、脏器受累情况。结果:37例患者均顺利完成检查,未发现并发症,图像质量满足诊断要求。结/直肠癌12例,转移癌伴肠梗阻3例,肠道间质瘤3例,小肠淋巴瘤2例,十二指肠癌及小肠黑色素瘤各1例,单纯性粘连性肠梗阻5例,回盲部感染及慢性肉芽肿性炎各3例,自身免疫性疾病2例,肠系膜扭转2例,所有病例磁共振检查均能发现病变,磁共振诊断结果与手术、病理或临床诊断符合率达89%。结论:3D Vibe冠状位多期动态增强扫描对肠道病变的诊断具有明显的优越性,是肠道磁共振成像中非常重要的检查序列。Objective： To analyze the performance of magnetic resonance enancer in the diagnosis of intestinal diseases which to evaluate the value of ultra-fast and high-resolution 3-T MR VIBE sequence in the diagnosis of intestinal diseases. Methods： From January 2015 to September 2017,37 patients with clinically diagnosed intestinal diseases underwent multi-phase dynamic enhanced coronary angiography of T1 WI,T2 WI,DWI and 3 D Vibe in routine MR. Through the obtained image data,and then analyzed the lesion site,lesion enhancement features,intestinal wall thickness,intestinal diameter and surrounding tissue,organ involvement. Results： The 37 patients completed the examination successfully. No complications were found and the image quality met the diagnostic requirements. 12 cases of node/rectum cancer,3 cases of metastasis with intestinal obstruction,3 cases of intestinal stromal tumor,2 cases of small intestine lymphoma,1 case of duodenal cancer and small intestine melanoma,5 cases of simple adhesive intestinal obstruction,Ileocecal infection and chronic granulomatous inflammation in 3 cases,2 cases of autoimmune diseases,mesenteric torsion in 2 cases,all the patients could be found in the magnetic resonance imaging lesions,magnetic resonance diagnostic findings and surgical,pathological or clinical diagnosis of coincidence rate Up to 89%. Conclusion： 3 D Vibe multi-phase dynamic contrast-enhanced coronary angiography has obvious superiority in the diagnosis of intestinal diseases. It was a very important examination sequence in intestinal magnetic resonance imaging.
