Accurate colon segmentation is a labor-intensive task, prone to interobserver variability. This study presents a method for automatic colon segmentation in T2-weighted MRI images, using 297 MRI scans from 72 healthy subjects and a neural network based on the 2D U-Net architecture. The presented network provided a Dice similarity coefficient (DSC) of 0.82 \u00b1 0.04 when compared to ground truth data (p=0.722), allowing for accurate evaluations of colonic physiology. The estimated colonic volumes were significantly correlated with the ground truth volumes with no tendency for over- or underestimation (p&lt;0.001). This study is, to our knowledge, the first to fully automatically segment the colon using MRI data, thus providing a method for objective colon evaluation without radiation exposure or disturbance of its physiology.<\/jats:p>","DOI":"10.3233\/shti260104","type":"book-chapter","created":{"date-parts":[[2026,5,21]],"date-time":"2026-05-21T21:55:27Z","timestamp":1779400527000},"source":"Crossref","is-referenced-by-count":0,"title":["Fully Automated Colon Delineation and Volume Estimation in T2-Weighted MRI with a 2D U-Net"],"prefix":"10.3233","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2394-0508","authenticated-orcid":false,"given":"Maciej","family":"Plocharski","sequence":"first","affiliation":[{"name":"Department of Health Science and Technology, Aalborg University, Aalborg, Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gry B.","family":"Hvaas","sequence":"additional","affiliation":[{"name":"Department of Health Science and Technology, Aalborg University, Aalborg, Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maria G.","family":"M\u00f8ller","sequence":"additional","affiliation":[{"name":"Department of Health Science and Technology, Aalborg University, Aalborg, Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nicolaj S.","family":"Thostrup","sequence":"additional","affiliation":[{"name":"Department of Health Science and Technology, Aalborg University, Aalborg, Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Frederik","family":"Samuelsen","sequence":"additional","affiliation":[{"name":"Department of Health Science and Technology, Aalborg University, Aalborg, Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4176-7430","authenticated-orcid":false,"given":"Esben B.","family":"Mark","sequence":"additional","affiliation":[{"name":"Mech-Sense, Department of Gastroenterology and Hepatology, Aalborg University Hospital, Aalborg, Denmark"},{"name":"Department of Clinical Medicine, Aalborg University, Aalborg, Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"7437","container-title":["Studies in Health Technology and Informatics","Opening the Personal Gate between Technology and Health Care"],"original-title":[],"link":[{"URL":"https:\/\/ebooks.iospress.nl\/pdf\/doi\/10.3233\/SHTI260104","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,5,21]],"date-time":"2026-05-21T21:55:27Z","timestamp":1779400527000},"score":1,"resource":{"primary":{"URL":"https:\/\/ebooks.iospress.nl\/doi\/10.3233\/SHTI260104"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,5,21]]},"ISBN":["9781643686615"],"references-count":0,"URL":"https:\/\/doi.org\/10.3233\/shti260104","relation":{},"ISSN":["0926-9630","1879-8365"],"issn-type":[{"value":"0926-9630","type":"print"},{"value":"1879-8365","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,5,21]]}}}
