[Radiological diagnosis of non-neoplastic bowel diseases]

Intestinal non-neoplastic diseases, including inflammation, bleeding and trauma, are common and frequently-occurring diseases. With the development of diagnosis and the change of disease spectrum, more and more clinical attentions are paid to autoimmune intestinal colitis, Crohn's disease, irritable bowel syndrome, ischemic bowel disease, intestinal polyps and other non-neoplastic diseases. Radiological modalities and characteristics of non-neoplastic bowel diseases are summarized and evaluated in this article. We hope to provide useful information for clinicians to select radiologic methods correctly.
