MRI诊断炎性肠病的应用进展

Application progresses of MRI in diagnosis of inflammatory bowel disease

炎性肠病(IBD)是一组慢性非特异性炎性疾病,主要包括克罗恩病和溃疡性结肠炎,其病程较长,病情轻重不一,易反复发作、迁延不愈,最终导致肠道狭窄、甚至恶变。对于IBD的治疗策略与疾病的活动性及严重程度相关。MRI技术的快速发展为诊断IBD提供了新的选择。本文就常规MRI及其新技术在IBD诊断中的应用进展进行综述。

Inflammatory bowel disease(IBD)is a group of chronic nonspecific inflammatory diseases,including Crohn's disease(CD)and ulcerative colitis(UC).IBD has a long course of disease,different severity of illness,easy recurrence and prolonged unhealed,and eventually leads to intestinal narrowing and even malignant transformation.The treatment strategies of IBD are related to the activity and severity of the disease.The rapid development of MRI technology provides a new choice of diagnosis for IBD.The application progresses of conventional MRI and relative new technologies in diagnosis of IBD were reviewed in this article.
