On the CT images, the vagina and uterine horns, body, and cervix were assessed for diameter, attenuation, and contrast enhancement pattern. In the retrospective study, CT features of large vaginal lesions (leiomyoma, leiomyosarcoma, adenocarcinoma, hematocolpos, and Gartner\u2019s duct cyst) were assessed in 5 bitches.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"sc_a4\">\n<jats:title>RESULTS<\/jats:title>\n<jats:p>In normal bitches, the cervix was thicker with strong central enhancement compared to the uterus and vagina. The uterine artery, which enters the mesometrium at the level of the cervix, was clearly visualized and assisted in identifying the cervix. In bitches with large vaginal masses, uterine arteries were displaced by the lesions and could not be used to locate the cervix. In 4\/5 dogs with vaginal masses, identification of the cervix allowed the determination of the organ of origin. In 1 dog with adenocarcinoma, CT vaginography was additionally required for determining the origin of mass.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"sc_a5\">\n<jats:title>CLINICAL RELEVANCE<\/jats:title>\n<jats:p>Results from this study indicate that the cervix, recognized in CT as focal thickening of the uterus with central enhancement, may be used as a landmark for the differentiation between the uterus and vagina in bitches.<\/jats:p>\n<\/jats:sec>","DOI":"10.2460\/ajvr.22.03.0052","type":"journal-article","created":{"date-parts":[[2022,11,24]],"date-time":"2022-11-24T16:55:18Z","timestamp":1669308918000},"page":"1-9","source":"Crossref","is-referenced-by-count":4,"title":["Computed tomography can differentiate vaginal-origin from uterine-origin lesions in bitches"],"prefix":"10.2460","author":[{"given":"Jin-Woo","family":"Jung","sequence":"first","affiliation":[{"name":"Department of Veterinary Medical Imaging, College of Veterinary Medicine, Chonnam National University, Gwangju, South Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Eunji","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Veterinary Medical Imaging, College of Veterinary Medicine, Chonnam National University, Gwangju, South Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Soyeon","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Veterinary Medical Imaging, College of Veterinary Medicine, Chonnam National University, Gwangju, South Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Seungjo","family":"Park","sequence":"additional","affiliation":[{"name":"Department of Veterinary Medical Imaging, College of Veterinary Medicine, Chonnam National University, Gwangju, South Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sang-kwon","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Veterinary Medical Imaging, College of Veterinary Medicine, Kyungpook National University, Daegu, South Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sunghwa","family":"Hong","sequence":"additional","affiliation":[{"name":"Department of Veterinary Diagnostic Imaging, Helix Animal Medical Center, Seoul, South Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jihye","family":"Choi","sequence":"additional","affiliation":[{"name":"Department of Veterinary Medical Imaging, College of Veterinary Medicine, Seoul National University, Seoul, South Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1272","reference":[{"issue":"5","key":"B1","series-title":"J Am Anim Hosp Assoc","doi-asserted-by":"publisher","first-page":"330","DOI":"10.5326\/JAAHA-MS-6130","article-title":"Radiographic and ultrasonographic findings of uterine neoplasms in nine dogs","volume":"50","author":"Patsikas M","year":"2014","unstructured":"Patsikas M, Papazoglou LG, Jakovljevic S, et al.
