炎症性腸疾患（IBD）の診療において，超音波やCTは，単に内視鏡やX線造影の代替法にとどまらず，貫壁性，さらには壁外の変化も把握することが可能なことから，その初期診断，活動性評価，合併症の診断などに有用である．比較的新しい技術としては，造影超音波による微細血流の評価，エラストグラフィーによる病変の硬度の評価などが挙げられ，CTではわかりやすい表示法としてのCT colonography（CTC）などが注目されている．IBDの治療法が進歩し，治療に対する概念も変化しつつある中で，病変局所の活動性評価は従来に増して重要となっているが，頻回に経過観察を要する本疾患においては，今後超音波やCTなどの苦痛の少ない検査法の活用が期待される．
