Treatment planning was guided by computed tomography\u2013magnetic resonance imaging (CT\u2013MRI) fusion for precise target delineation near the globe. Serial CT and MRI up to 12 months after treatment showed transient enlargement of intratumoral cysts with fluid\u2013fluid levels immediately after treatment, indicating pseudoprogression, followed by marked tumor regression. Progressive cortical remodeling and re\u2010ossification restored normal bone contours. These findings present the value of multimodal imaging in radiotherapy planning and follow\u2010up of head and neck tumors to distinguish pseudoprogression from tumor growth and identify postradiation bone regeneration.<\/jats:p>","DOI":"10.1111\/vru.70190","type":"journal-article","created":{"date-parts":[[2026,5,23]],"date-time":"2026-05-23T06:01:56Z","timestamp":1779516116000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["CT\u2013MRI Fusion for Radiation Treatment Planning and Serial Imaging of a Canine Maxillofacial Osteosarcoma"],"prefix":"10.1111","volume":"67","author":[{"ORCID":"https:\/\/orcid.org\/0009-0008-5088-0321","authenticated-orcid":false,"given":"Nahyun","family":"Kwon","sequence":"first","affiliation":[{"name":"Department of Veterinary Medical Imaging College of Veterinary Medicine and Research Institute for Veterinary Science Seoul National University  Seoul South Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8819-9576","authenticated-orcid":false,"given":"Soyeon","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Veterinary Medical Imaging College of Veterinary Medicine and Research Institute for Veterinary Science Seoul National University  Seoul South Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0008-8955-1373","authenticated-orcid":false,"given":"Sunghwa","family":"Hong","sequence":"additional","affiliation":[{"name":"Department of Veterinary Medical Imaging College of Veterinary Medicine and Research Institute for Veterinary Science Seoul National University  Seoul South Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5614-9846","authenticated-orcid":false,"given":"Minok","family":"Ryu","sequence":"additional","affiliation":[{"name":"Laboratory of Internal Medicine College of Veterinary Medicine and Research Institute for Veterinary Science Seoul National University  Seoul South Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2077-763X","authenticated-orcid":false,"given":"Junghee","family":"Yoon","sequence":"additional","affiliation":[{"name":"Department of Veterinary Medical Imaging College of Veterinary Medicine and Research Institute for Veterinary Science Seoul National University  Seoul South Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1258-7158","authenticated-orcid":false,"given":"Jihye","family":"Choi","sequence":"additional","affiliation":[{"name":"Department of Veterinary Medical Imaging College of Veterinary Medicine and Research Institute for Veterinary Science Seoul National University  Seoul South Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,5,22]]},"reference":[{"key":"e_1_2_10_2_1","doi-asserted-by":"publisher","DOI":"10.1292\/jvms.15-0627"},{"key":"e_1_2_10_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0046-8177(99)90297-6"},{"key":"e_1_2_10_4_1","doi-asserted-by":"publisher","DOI":"10.1111\/vru.13291"},{"key":"e_1_2_10_5_1","doi-asserted-by":"publisher","DOI":"10.4103\/0019-5413.132491"},{"key":"e_1_2_10_6_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1476-5829.2012.00352.x"},{"key":"e_1_2_10_7_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1939-1676.2001.tb01242.x"},{"key":"e_1_2_10_8_1","doi-asserted-by":"publisher","DOI":"10.1111\/vco.12960"},{"key":"e_1_2_10_9_1","doi-asserted-by":"publisher","DOI":"10.1259\/dmfr.20190202"},{"key":"e_1_2_10_10_1","doi-asserted-by":"publisher","DOI":"10.4102\/jsava.v75i4.476"},{"key":"e_1_2_10_11_1","doi-asserted-by":"publisher","DOI":"10.4329\/wjr.v3.i5.125"},{"issue":"7","key":"e_1_2_10_12_1","first-page":"707","article-title":"Palliative Radiation Therapy for Canine Osteosarcoma","volume":"47","author":"Mayer M.
