The present study investigates this finding by comparing 13 measures of six cadaveric equine digits collected with the following workflows: radiographs with 1 and 2\u2009m focus\u2010object distance (FOD) (Xray 1\u2009m\/2\u2009m), computed tomography images in planes defined based on anatomical landmarks (CTw), simulated radiographs based on the tomography dataset (virtual 120\u2010mm slabs, Xray Sim) and measurements based on slices and projections aided by three\u2010dimensional reconstruction models of hooves and bones based on the tomography data set (AMIRA). Furthermore, Xray 1\u2009m\/2\u2009m values were mathematically corrected using factors calculated for each hoof (Xray 1\u2009m\/2\u2009m corr). Results of all methods correlated, but absolute values showed differences. Xray 1\u2009m\/2\u2009m values were systematically higher, Xray Sim and AMIRA values were lower than CTw values. Increasing FOD and mathematical correction of Xray values led to approximation to CTw values. Among measures producing unexpected results and large differences between methods were palmar process height, medial and lateral (but not dorsal) hoof wall thickness, dorsal hoof wall length, weight\u2010bearing length and heel\/toe to plumbline. Explanations might be primarily different definitions of landmarks in different methods, but also contrast settings for displaying both bone and soft tissue contours. Therefore, when comparing the measuring results collected using different methods, it is advisable to analyse relative rather than absolute values.<\/jats:p>","DOI":"10.1111\/ahe.70073","type":"journal-article","created":{"date-parts":[[2025,12,15]],"date-time":"2025-12-15T09:21:25Z","timestamp":1765790485000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Measuring Equine Hooves in Radiographs and Computed Tomography Images Reveals Unexpected Size Differences"],"prefix":"10.1111","volume":"55","author":[{"given":"Lina","family":"Sellke","sequence":"first","affiliation":[{"name":"Department of Biological Sciences and Pathobiology, Unit of Morphology University of Veterinary Medicine Vienna  Vienna Austria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Eberhard","family":"Ludewig","sequence":"additional","affiliation":[{"name":"Diagnostic Imaging \u2013 Clinical Center of Small Animals, Clinical Department for Small Animals and Horses University of Veterinary Medicine, Vienna  Vienna Austria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2140-7892","authenticated-orcid":false,"given":"Stephan","family":"Handschuh","sequence":"additional","affiliation":[{"name":"VetCore Facility for Research\/Imaging Unit University of Veterinary Medicine, Vienna  Vienna Austria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5388-8208","authenticated-orcid":false,"given":"Kirsti","family":"Witter","sequence":"additional","affiliation":[{"name":"Department of Biological Sciences and Pathobiology, Unit of Morphology University of Veterinary Medicine Vienna  Vienna Austria"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2025,12,15]]},"reference":[{"key":"e_1_2_10_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0140\u20106736(86)90837\u20108"},{"key":"e_1_2_10_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.tvjl.2019.01.012"},{"key":"e_1_2_10_4_1","doi-asserted-by":"publisher","DOI":"10.1148\/rg.337125204"},{"key":"e_1_2_10_5_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.2042\u20103306.2001.tb05358.x"},{"key":"e_1_2_10_6_1","doi-asserted-by":"publisher","DOI":"10.1002\/mp.14142"},{"key":"e_1_2_10_7_1","doi-asserted-by":"publisher","DOI":"10.1259\/dmfr\/13603271"},{"key":"e_1_2_10_8_1","doi-asserted-by":"publisher","DOI":"10.12659\/PJR.901939"},{"issue":"3","key":"e_1_2_10_9_1","first-page":"499","article-title":"Multichannel Computed Tomography Versus Cone\u2010Beam Computed Tomography: Linear Accuracy of In\u00a0Vitro Measurements of the Maxilla for Implant Placement","volume":"25","author":"Fatemitabar S.
