PURPOSE
Evaluation of hydro-MRI in the diagnosis of chronic inflammatory bowel disease (IBD).
MATERIAL AND METHODS
33 patients with suspected Crohn's disease or ulcerative colitis were studied prospectively. After distension of the colon by a rectal enema, breathhold MR imaging was performed during bowel relaxation. Results were compared to the clinical diagnosis, endoscopy, barium studies and histopathology.
RESULTS
24/24 patients with active Crohn's disease were correctly diagnosed by MRI. Conversely, MRI was positive in only 2/5 patients with ulcerative colitis. In 5 patients the presence of IBD was excluded. There were no false positives.
CONCLUSION
Hydro-MRI is a very reliable modality in the diagnosis of Crohn's disease. In the differentiation of Crohn's disease from ulcerative colitis, hydro-MRI seems to be a promising imaging procedure.
目的
评估水磁共振成像（hydro-MRI）在慢性炎症性肠病（IBD）诊断中的作用。
材料与方法
对33例疑似克罗恩病或溃疡性结肠炎的患者进行前瞻性研究。通过直肠灌肠使结肠扩张后，在肠道松弛时进行屏气磁共振成像。将结果与临床诊断、内镜检查、钡剂造影和组织病理学结果进行比较。
结果
24例活动性克罗恩病患者均被MRI正确诊断。相反，MRI仅在5例溃疡性结肠炎患者中的2例呈阳性。5例患者被排除患有IBD。无假阳性结果。
结论
水磁共振成像在克罗恩病的诊断中是一种非常可靠的方法。在区分克罗恩病和溃疡性结肠炎方面，水磁共振成像似乎是一种有前景的成像检查方法。
