The development of accurate and rapid detection approaches is of essential importance for early diagnosis and timely management of GI diseases. This review mainly focuses on the imaging of several representative gastrointestinal ailments, such as inflammatory bowel disease, tumors, appendicitis, Meckel\u2019s diverticulum, and others. Various imaging modalities commonly used for the gastrointestinal tract, including magnetic resonance imaging (MRI), positron emission tomography (PET) and single photon emission computed tomography (SPECT), and photoacoustic tomography (PAT) and multimodal imaging with mode overlap are summarized. These achievements in single and multimodal imaging provide useful guidance for improved diagnosis, staging, and treatment of the corresponding gastrointestinal diseases. The review evaluates the strengths and weaknesses of different imaging techniques and summarizes the development of imaging techniques used for diagnosing gastrointestinal ailments.<\/jats:p>","DOI":"10.3390\/jimaging9060115","type":"journal-article","created":{"date-parts":[[2023,6,8]],"date-time":"2023-06-08T03:29:48Z","timestamp":1686194988000},"page":"115","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":16,"title":["Imaging of Gastrointestinal Tract Ailments"],"prefix":"10.3390","volume":"9","author":[{"given":"Boyang","family":"Sun","sequence":"first","affiliation":[{"name":"Key Laboratory of Systems Bioengineering, School of Chemical Engineering and Technology, Frontiers Science Center for Synthetic Biology (Ministry of Education), Tianjin University, Tianjin 300350, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jingang","family":"Liu","sequence":"additional","affiliation":[{"name":"Key Laboratory of Systems Bioengineering, School of Chemical Engineering and Technology, Frontiers Science Center for Synthetic Biology (Ministry of Education), Tianjin University, Tianjin 300350, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Silu","family":"Li","sequence":"additional","affiliation":[{"name":"Key Laboratory of Systems Bioengineering, School of Chemical Engineering and Technology, Frontiers Science Center for Synthetic Biology (Ministry of Education), Tianjin University, Tianjin 300350, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9052-884X","authenticated-orcid":false,"given":"Jonathan F.","family":"Lovell","sequence":"additional","affiliation":[{"name":"Department of Biomedical Engineering, The State University of New York at Buffalo, Buffalo, NY 14260, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yumiao","family":"Zhang","sequence":"additional","affiliation":[{"name":"Key Laboratory of Systems Bioengineering, School of Chemical Engineering and Technology, Frontiers Science Center for Synthetic Biology (Ministry of Education), Tianjin University, Tianjin 300350, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,6,8]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"519","DOI":"10.1007\/s10620-012-2371-5","article-title":"Recent Trends in the Prevalence of Crohn\u2019s Disease and Ulcerative Colitis in a Commercially Insured US Population","volume":"58","author":"Kappelman","year":"2013","journal-title":"Dig.
