Perceived patient experience was recorded using a 5-point visual analogue scale (VAS) before and after the examination. Movements of the head and body were quantified and characterized from video recordings of the scan. Multiple linear regression analyses were applied to evaluate associations between log-transformed movement and age, sex, and VAS scores. Separate regression models were applied for pre- and post-scan VAS. Significance level was set at .05.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Number of movements during scan time was registered for the head separately (mean\/median 6.3\/0, range 0-82) and for the body in total (62\/34, 0-430). Increased head movement was significantly associated with younger age (34%\/year, P\u2009=\u2009.010). Overall movement was significantly associated with sex (M\u2009&amp;gt;\u2009F, 24.8% more movement, P\u2009=\u2009.010). Pre-scan VAS (mean\/median 1.73\/2, range 1-3) decreased significantly with increasing age (0.21 points\/year, P\u2009=\u2009.035). Post-scan VAS (1.95\/2, 1-3) was significantly higher in girls than in boys (0.6 points\/year, P\u2009=\u2009.031).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Age and sex influence the child\u2019s experience and the number of movements during the mock scan. ddMRI may prove to be a feasible method for scanning children in a dental setting, offering a comfortable experience without ionizing radiation.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Advances in knowledge<\/jats:title>\n                    <jats:p>This article is the first to demonstrate the applicability of ddMRI in a pediatric population, thereby laying the groundwork for future research into its use in diagnosis and treatment planning for children and adolescents<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1093\/dmfr\/twag049","type":"journal-article","created":{"date-parts":[[2026,7,13]],"date-time":"2026-07-13T05:10:47Z","timestamp":1783919447000},"source":"Crossref","is-referenced-by-count":0,"title":["Patient experience and movement frequency in young children during simulated ddMRI examinations"],"prefix":"10.1093","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5342-0143","authenticated-orcid":false,"given":"Anne Birkeholm","family":"Jensen","sequence":"first","affiliation":[{"name":"Section for Oral Ecology, Pediatric Dentistry, Department of Dentistry and Oral Health, Aarhus University , Aarhus 8000,","place":["Denmark"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4758-4723","authenticated-orcid":false,"given":"Louise Hauge","family":"Matzen","sequence":"additional","affiliation":[{"name":"Section for Oral Radiology and Endodontics, Department of Dentistry and Oral Health, Aarhus, University , Aarhus 8000,","place":["Denmark"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0007-0002-2161","authenticated-orcid":false,"given":"Jennifer Heather","family":"Christensen","sequence":"additional","affiliation":[{"name":"Section for Oral Radiology and Endodontics, Department of Dentistry and Oral Health, Aarhus, University , Aarhus 8000,","place":["Denmark"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2026,7,11]]},"reference":[{"key":"2026072112463491300_twag049-B1","doi-asserted-by":"publisher","first-page":"429","DOI":"10.1007\/s40368-020-00532-y","article-title":"Diagnostic efficacy of and indications for intraoral radiographs in pediatric dentistry: a systematic review","volume":"21","author":"Aps","year":"2020","journal-title":"Eur Arch Paediatr Dent"},{"key":"2026072112463491300_twag049-B2","doi-asserted-by":"publisher","first-page":"583","DOI":"10.1259\/dmfr\/20920453","article-title":"Dose distribution for dental cone beam CT and its implication for defining a dose index","volume":"41","author":"Pauwels","year":"2012","journal-title":"Dentomaxillofac Radiol"},{"key":"2026072112463491300_twag049-B3","volume-title":"Cone Beam CT for Dental and Maxillofacial Radiology \u2013 Evidence-Based Guidelines","author":"Commission E, Energy D-Gf","year":"2012"},{"key":"2026072112463491300_twag049-B4","doi-asserted-by":"crossref","first-page":"1057","DOI":"10.3390\/ijerph13111057","article-title":"Pediatric exposures to ionizing radiation: carcinogenic considerations","volume":"13","author":"Kutanzi","year":"2016","journal-title":"IJERPH"},{"key":"2026072112463491300_twag049-B5","first-page":"185","volume-title":"Str\u00e5lebogen for Tandfagligt Personale.","author":"Petersen AWMW","year":"2018"},{"key":"2026072112463491300_twag049-B6","doi-asserted-by":"publisher","first-page":"1","DOI":"10.1093\/ejo\/cjad062","article-title":"Will supplemental cone beam computed tomography change the treatment plan of impacted maxillary canines based on 2D radiography?
