【摘要】 目的探讨小肠磁共振水成像检查方法及其对小肠疾病的诊断价值。方法本组28例小肠磁共振水成像。25例检查前30min口服0.9%氯化钠注射液或5%葡萄糖氯化钠注射液1500ml,检查前10min静脉注射山莨菪碱20mg;3例小肠梗阻直接进行小肠磁共振水成像,6例增强扫描。诊断结果与插管法小肠气钡造影结果对照。部分病例经手术、病理证实。结果28例小肠磁共振水成像检查均获得成功,图像质量满足诊断要求。正常小肠10例,Crohn’s病2例,十二指肠乳头癌3例,十二指肠腺瘤样增生1例,十二指肠憩室2例,小肠腺癌3例,回肠息肉1例,空肠间质瘤2例,回肠梗阻3例,小肠系膜扭转1例。18例小肠器质性病变诊断敏感性100%(18/18),特异性77.8%(14/18)。结论磁共振水成像对小肠病变的诊断是一种有效的检查方法。更多还原

【Abstract】 Objective To evaluate the technique and diagnosis of small bowel diseases with Hydro-MRI.Methods 28 patients with suspected small bowel diseases underwent small intestinal Hydro-MRI.Oral administration of 1500 ml of 0.9% sodium chloride or 5% glucose sodium chloride pre-examination 30 min and intravenous injection 20 mg of anisodamine pre-examination 10 min.The other 3 patients with small bowel obstruction were directly undergone Hydro-MRI.Contrast-enhanced MR imaging was performed in 6 patients.The results of Hydro-MRI were compared,with that of small intestinal double contrast examination.A part of patients were confirmed by operation and pathology.Results The intestinal Hydro-MRI in 28 patients was successful,and the images were fine.Of 28 cases,10 were normal,others included 2 of Crohn’s diseases,3 of duodenal papilloma,one of duodenal adenomatoid hyperplasia,3 of small bowel adenocarcinoma,3 of ileal obstruction,2 of duodenal diverticulum,2 of jejunal stromal tumor,one of ileal polyp and small intestinal malrotation respectively.The sensitivity in diagnosing small intestinal diseases was 100%(18/18),and the specificity was 77.8%(14/18).Conclusion Hydro-MRI is a sensitive method in diagnosis of small bowel disease.更多还原
