BACKGROUND
This study focuses on the correlation of the signal intensity (SI) of the bowel wall in magnetic resonance (MR) colonography with the inflammation activity in Crohn's disease.
MATERIAL AND METHODS
We performed MR colonography in 42 patients and compared the change of the SI of the bowel wall (T1-weighted/paramagnetic contrast medium) with colonoscopic findings.
RESULTS
Change of the SI and colonoscopically assessed inflammatory activity are significantly correlated (r=.676, P<or=.01).
CONCLUSION
The degree of the contrast enhancement of the bowel wall may be a criterion for the degree of inflammation in Crohn's disease.
背景
本研究聚焦于磁共振（MR）结肠成像中肠壁信号强度（SI）与克罗恩病炎症活动的相关性。
材料与方法
我们对42例患者进行了MR结肠成像，并将肠壁的SI变化（T1加权/顺磁性造影剂）与结肠镜检查结果进行了比较。
结果
SI变化与结肠镜评估的炎症活动显著相关（r = 0.676，P≤0.01）。
结论
肠壁对比增强程度可能是克罗恩病炎症程度的一个标准。
