影像学诊断在炎症性肠病中的应用

Application of Imaging Diagnosis in Inflammatory Bowel Diseases

炎症性肠病(IBD)包括克罗恩病和溃疡性结肠炎等,其确诊需要结合临床表现、内镜、影像学及病理学检查。影像学是临床诊断IBD的重要依据,其能弥补内镜观察的不足,是IBD患者随访复查、评估病情的常用工具。传统X线造影仅能观察肠腔及黏膜,相比之下,超声、CT、磁共振成像等可更全面、更敏感地观察IBD,各种检查都存在优势和不足,现对各种影像学检查方法诊断IBD的优缺点进行综述。

Inflammatory bowel disease（IBD） includes Crohn＇s disease and ulcerative colitis.IBD diagnosis requires comprehensive analysis of clinical manifestations,endoscope,imaging and pathological examination.Im-aging is an important method for clinical diagnosis,which can compensate for the lack of endoscopic views,and is a common tool for IBD follow-up or pathogenetic condition assessment.Traditional X-ray can only enable the observation on the enteric cavity and mucous membrane.In contrast,ultrasound,CT,MRI and other methods are more comprehensive and sensitive to observe the IBD ,and these examinations all have own strengths and weak-nesses.
