磁共振小肠灌肠论文文献综述
Albert,J.G,Martiny,F,Krummenerl,A.,W.E.,Fleig,郑世成[1]（2006）在《小肠克罗恩病的诊断:一项胶囊内镜、磁共振成像及X线灌肠透视的前瞻性研究》一文中研究指出Background and aims: The diagnostic yield of capsule endoscopy (CE) compared with magnetic resonance imaging (MRI) in small bowel Crohn‘s disease is not well established. We prospectively investigated CE, MRI, and double contrast fluoroscopy in patients with suspected small bowel Crohn‘s disease. Methods: Fifty two consecutive patients (39 females, 13 males) were investigated by MRI, fluorosco py and if bowel obstruction could be excluded-by CE. In 25, Crohn‘s disease wa s newly suspected while the diagnosis of Crohn‘s disease (non-small bowel) had been previously established in 27. Results: Small bowel Crohn‘s disease was di agnosed in 41 of 52 patients (79%). CE was not accomplished in 14 patients due to bowel strictures. Of the remaining 27 patients, CE, MRI, and fluoroscopy dete cted small bowel Crohn‘s disease in 25 (93%), 21 (78%), and 7 (of 21; 33%) c ases, respectively. CE was the only diagnostic tool in four patients. CE was sli ghtly more sensitive than MRI (12 v 10 of 13 in suspected Crohn‘s disease and 1 3 v 11 of 14 in established Crohn‘s disease). MRI detected inflammatory conglom erates and enteric fistulae in three and two cases, respectively. Conclusion: CE and MRI are complementary methods for diagnosing small bowel Crohn‘s disease. CE is capable of detecting limited mucosal lesions that may be missed by MRI, bu t awareness of bowel obstruction is mandatory. In contrast, MRI is helpful in id entifying transmural Crohn‘s disease and extraluminal lesions, and may exclude strictures.(本文来源于《世界核心医学期刊文摘(胃肠病学分册)》期刊2006年04期）
Ochsenkühn,T,Herrmann,K,,Schoenberg,S,O[2]（2005）在《邻近回肠末端的小肠克罗恩病:磁共振注气小肠灌肠检查》一文中研究指出Background: Although Crohn disease (CD) can affect the entire alimentary tract, the proportion of patients with small bowel inflammation proximal to the terminal ileum is still unclear. Magnetic resonance imaging (MRI) combined with smallbowel enteroclysis can detect inflammatory lesions of the small bowel. Hence, we applied MR enteroclysis to assess the percentage of patients with small bowel inflammation proximal to the terminal ileum among patients with CD and abdominal pain. Methods: Twenty five consecutive patients with low, active CD of the colon and/or terminal ileum and episodes of abdominal pain were examined by both MR enteroclysis and conventional enteroclysis. The findings of MR enteroclysis were compared with endoscopic and histological results in the terminal ileum and conventional enteroclysis in the small bowel proximal to the terminal ileum. Results: In 13 of the 25 patients, inflammation of the small bowel proximal to the terminal ileum was shown by MR enteroclysis, whereas in only 4 of the 25 patients, signs of inflammation of the small bowel proximal to the terminal ileum were shown by conventional enteroclysis, all of which were demonstrated by MR enteroclysis. MR enteroclysis confirmed the findings in 22 of 25 patients in whom endoscopy and histology had shown inflammation (16 of 18) or no inflammation (6 of 7) of the terminal ileum. Conclusion: In symptomatic patients with CD even of low activity, inflammation of the small bowel proximal to the terminal ileum is frequent.(本文来源于《世界核心医学期刊文摘(胃肠病学分册)》期刊2005年03期）
