| [ Summary ] |
Crohn's disease (CD), unlike ulcerative colitis, which affects the mucosal surface, is characterized by transmural inflammation. The lesion of CD can develop discontinuously over the whole gastrointestine and spread over the extraintestinal areas of the abdomen. Owing to the characteristics of CD, crosssectional imaging techniques such as CT/MR enterography have become the gold standard imaging modalities of the diagnosis of CD. Whether the treatment goal of CD is transmural healing on cross-sectional imaging, not an endoscopic mucosal healing, is controversial. |
