This retrospective, multi\u2010center, analytical study aimed to evaluate the CT characteristics for the differentiation of adenocarcinoma, lymphoma, and spindle cell sarcoma (SCS) in dogs. Thirty\u2010seven dogs who underwent contrast CT and histopathological examinations were included (adenocarcinomas, n\u00a0=\u00a011; lymphomas, n\u00a0=\u00a012; SCS, n\u00a0=\u00a014). Quantitative and qualitative CT parameters, including tumor morphology, contrast enhancement pattern, Hounsfield unit (HU) value, and presence or absence of intraabdominal lymphadenopathy, were evaluated for each included small intestine tumor CT case. Adenocarcinomas tended to show endophytic growth, intestinal obstruction, and a heterogeneous enhancement pattern. Lymphomas tended to show exophytic growth, contrast enhancement of the intestinal tumor mucosal layer, a homogeneous enhancement pattern, and the presence of lymphadenopathies in the abdominal cavity. SCSs tended to show lobulated growth, a large cystic portion within the tumor, a heterogeneous enhancement pattern, a large size with fat stranding sign, and lower HU values in postcontrast images. Cut\u2010off values of the minimum diameter\/fifth lumbar vertebral mid\u2010body height (\u22655.80; area under the curve [AUC]\u00a0=\u00a00.97, <jats:italic>P<\/jats:italic>\u00a0&lt;\u00a00.001) and minimum HU value\/HU value of the aorta (\u22640.26; AUC\u00a0=\u00a00.96, <jats:italic>P<\/jats:italic>\u00a0&lt;\u00a00.001) were derived to discriminate SCS from the two other tumor types. In conclusion, contrast CT characteristics may be useful in differentiating small intestinal adenocarcinomas, lymphomas, and SCSs in dogs.<\/jats:p>","DOI":"10.1111\/vru.13174","type":"journal-article","created":{"date-parts":[[2023,1,3]],"date-time":"2023-01-03T08:10:43Z","timestamp":1672733443000},"page":"233-242","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Computed tomographic findings may be useful for differentiating small intestinal adenocarcinomas, lymphomas, and spindle cell sarcomas in dogs"],"prefix":"10.1111","volume":"64","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5619-9982","authenticated-orcid":false,"given":"Seonah","family":"Lee","sequence":"first","affiliation":[{"name":"Department of Veterinary Medical Imaging, College of Veterinary Medicine Konkuk University  Seoul Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jeongyeon","family":"Hwang","sequence":"additional","affiliation":[{"name":"Helix Animal Medical Center  Seoul Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hyunwook","family":"Kim","sequence":"additional","affiliation":[{"name":"Haemaru Referral Animal Hospital  Gyunggi\u2010do Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yeonjung","family":"Hong","sequence":"additional","affiliation":[{"name":"Western Animal Medical Center  Seoul Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gahyun","family":"Lee","sequence":"additional","affiliation":[{"name":"Haemaru Referral Animal Hospital  Gyunggi\u2010do Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Doori","family":"Chung","sequence":"additional","affiliation":[{"name":"Western Animal Medical Center  Seoul Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5728-4820","authenticated-orcid":false,"given":"Jaehwan","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Veterinary Medical Imaging, College of Veterinary Medicine Konkuk University  Seoul Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7989-0939","authenticated-orcid":false,"given":"Kidong","family":"Eom","sequence":"additional","affiliation":[{"name":"Department of Veterinary Medical Imaging, College of Veterinary Medicine Konkuk University  Seoul Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2023,1,3]]},"reference":[{"key":"e_1_2_11_2_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1740-8261.2002.tb01050.x"},{"key":"e_1_2_11_3_1","doi-asserted-by":"publisher","DOI":"10.2754\/avb201382040387"},{"key":"e_1_2_11_4_1","first-page":"460","volume-title":"Withrow & MacEwen's Small Animal Clinical Oncology","author":"Vail DM","year":"2020"},{"key":"e_1_2_11_5_1","doi-asserted-by":"publisher","DOI":"10.1111\/jsap.12324"},{"key":"e_1_2_11_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/B978-0-323-48247-9.00059-0"},{"key":"e_1_2_11_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/B978-0-323-53337-9.00021-6"},{"key":"e_1_2_11_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0195-5616(01)50063-7"},{"key":"e_1_2_11_9_1","doi-asserted-by":"publisher","DOI":"10.1102\/1470-7330.2007.0032"},{"key":"e_1_2_11_10_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1740-8261.2012.01969.x"},{"key":"e_1_2_11_11_1","doi-asserted-by":"publisher","DOI":"10.1002\/(SICI)1097-0258(19980430)17:8<857::AID-SIM777>3.0.CO;2-E"},{"key":"e_1_2_11_12_1","doi-asserted-by":"publisher","DOI":"10.1111\/vru.12153"},{"key":"e_1_2_11_13_1","doi-asserted-by":"publisher","DOI":"10.2214\/AJR.10.4375"},{"key":"e_1_2_11_14_1","first-page":"427","volume-title":"Brain Mapping: The Methods","author":"Toga AW","year":"2002"},{"key":"e_1_2_11_15_1","doi-asserted-by":"publisher","DOI":"10.1111\/vru.12075"},{"key":"e_1_2_11_16_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0016-5107(93)70159-5"},{"key":"e_1_2_11_17_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1939-1676.2003.tb01318.x"},{"key":"e_1_2_11_18_1","doi-asserted-by":"publisher","DOI":"10.1038\/nrc3726"},{"key":"e_1_2_11_19_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.copbio.2016.02.007"},{"key":"e_1_2_11_20_1","doi-asserted-by":"publisher","DOI":"10.1038\/s41422-018-0058-y"}],"container-title":["Veterinary Radiology &amp;
