As a cumulative effective dose (CED) \u2265 100 mSv is considered significant for stochastic risks of cancer, it is important to monitor and control the radiation exposure of the IBD patients. In the present work, we aimed to quantify the mean CED in IBD patients to assess any harmful effects of radiation.<jats:italic> Methods.<\/jats:italic> This study includes 200 IBD patients, identified retrospectively, from the outpatient clinics of the Centre Hospitalier de l\u2019Universit\u00e9 de Montr\u00e9al between January 1, 2010, and February 15, 2017, from the gastroenterologists\u2019 patients lists. The number and type of each radiology test performed were listed for each patient during the study period and the CED was calculated using our institution\u2019s dose index when available and standardized tables.<jats:italic> Results.<\/jats:italic> Among the 200 IBD patients, 157 patients had Crohn\u2019s disease (CD), 41 had ulcerative colitis (UC), and 2 had indeterminate colitis. The mean CED for IBD patients was 23.1 \u00b1 45.2 mSv during a mean follow-up duration of 4.3 years. CED was higher among patients with CD than with UC (27.5 \u00b1 49.5 versus 6.8 \u00b1 14.8 mSv; p&lt;0.01). Six patients were exposed to a high CED (&gt;100 mSv) and all had CD.<jats:italic> Conclusion.<\/jats:italic> While potentially harmful levels of radiation exposure are of concern in only a small number of patients, strategies to limit such exposure are encouraged when clinically appropriate.<\/jats:p>","DOI":"10.1155\/2019\/2030735","type":"journal-article","created":{"date-parts":[[2019,6,11]],"date-time":"2019-06-11T19:30:39Z","timestamp":1560281439000},"page":"1-5","source":"Crossref","is-referenced-by-count":9,"title":["Diagnostic Radiation Exposure in Patients with Inflammatory Bowel Disease"],"prefix":"10.1155","volume":"2019","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7658-1014","authenticated-orcid":true,"given":"Catherine","family":"Langevin","sequence":"first","affiliation":[{"name":"Gastroenterology Division, Centre Hospitalier de l\u2019Universit\u00e9 de Montr\u00e9al, Quebec, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lysanne","family":"Normandeau","sequence":"additional","affiliation":[{"name":"Health Physicist, Centre Hospitalier de l\u2019Universit\u00e9 de Montr\u00e9al, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4272-6793","authenticated-orcid":true,"given":"Mickael","family":"Bouin","sequence":"additional","affiliation":[{"name":"Gastroenterology Division, Centre Hospitalier de l\u2019Universit\u00e9 de Montr\u00e9al, Quebec, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.3748\/wjg.v20.i29.9872"},{"key":"2","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.2235592100"},{"key":"3","doi-asserted-by":"publisher","DOI":"10.1097\/01.HP.0000326333.42287.a2"},{"key":"4","doi-asserted-by":"publisher","DOI":"10.1016\/j.cgh.2011.09.005"},{"key":"5","doi-asserted-by":"publisher","DOI":"10.4065\/mcp.2010.0260"},{"key":"6","doi-asserted-by":"publisher","DOI":"10.1259\/bjr\/25026140"},{"key":"7","volume-title":"Position statement of the health physics society"},{"key":"8","doi-asserted-by":"publisher","DOI":"10.3748\/wjg.v22.i7.2165"},{"key":"9","series-title":"Annals of the ICRP 37 (2-4)","volume":"103","year":"2007"},{"key":"10","year":"2012"},{"key":"11","doi-asserted-by":"publisher","DOI":"10.1148\/radiol.2481071451"},{"key":"12","doi-asserted-by":"publisher","DOI":"10.1093\/rpd\/ncr024"}],"container-title":["Canadian Journal of Gastroenterology and Hepatology"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/journals\/cjgh\/2019\/2030735.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/cjgh\/2019\/2030735.xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/cjgh\/2019\/2030735.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2019,6,11]],"date-time":"2019-06-11T19:30:40Z","timestamp":1560281440000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.hindawi.com\/journals\/cjgh\/2019\/2030735\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2019,6,11]]},"references-count":12,"alternative-id":["2030735","2030735"],"URL":"https:\/\/doi.org\/10.1155\/2019\/2030735","relation":{},"ISSN":["2291-2789","2291-2797"],"issn-type":[{"value":"2291-2789","type":"print"},{"value":"2291-2797","type":"electronic"}],"subject":[],"published":{"date-parts":[[2019,6,11]]}}}
