Computed tomography is used for abdominal, thoracic, or whole body imaging in staging mast cell tumors in the authors\u2019 institution enabling evaluation of multiple body areas in one examination. The aim of this study was to compare the CT examinations acquired for staging of mast cell disease to their subsequent liver and spleen cytology findings. Medical records of dogs with primary mast cell tumors that underwent abdominal CT and concurrent liver and spleen aspirates were reviewed. The CT examinations were evaluated for attenuation, size, and margination of the liver and spleen. The relationship between CT findings and cytology results was analyzed. Forty\u2010nine dogs matched the inclusion criteria: five of forty\u2010nine dogs with cutaneous mast cell tumors were positive for metastasis from liver and\/or spleen aspirates. Of the five dogs with cytological evidence of liver or spleen metastasis, four had normal CT liver attenuation and size, one dog had concurrent primary hepatocellular neoplasia, four dogs had abnormal splenic parenchyma (two nodular and two diffuse heterogeneity), and one dog had a normal attenuation of the spleen. In four dogs, the spleen was subjectively enlarged. Computed tomographic evaluation of the liver showed no consistent pattern associated with mast cell metastasis and did not predict cytology results. Multifocal splenic hypoattenuating lesions more commonly coincided with mast cell metastasis. Sampling of the liver and spleen remains to be considered in the absence of abnormal CT findings for full staging.<\/jats:p>","DOI":"10.1111\/vru.12717","type":"journal-article","created":{"date-parts":[[2019,2,21]],"date-time":"2019-02-21T00:54:25Z","timestamp":1550710465000},"page":"306-315","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":18,"title":["Abdominal CT evaluation of the liver and spleen for staging mast cell tumors in dogs yields nonspecific results"],"prefix":"10.1111","volume":"60","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6895-4527","authenticated-orcid":false,"given":"Jonathan R","family":"Hughes","sequence":"first","affiliation":[{"name":"Department of Clinical Sciences and Services The Royal Veterinary College  North Mymms Hatfield AL9 7TA UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1926-3455","authenticated-orcid":false,"given":"Balazs","family":"Szladovits","sequence":"additional","affiliation":[{"name":"Department of Pathobiology and Population Sciences Hawkshead Lane  North Mymms Hatfield AL9 7TA UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3050-072X","authenticated-orcid":false,"given":"Randi","family":"Drees","sequence":"additional","affiliation":[{"name":"Department of Clinical Sciences and Services The Royal Veterinary College  North Mymms Hatfield AL9 7TA UK"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2019,2,20]]},"reference":[{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1476-5829.2012.00341.x"},{"key":"e_1_2_6_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/B978-1-4377-2362-5.00020-7"},{"key":"e_1_2_6_4_1","doi-asserted-by":"publisher","DOI":"10.1136\/vr.158.9.287"},{"key":"e_1_2_6_5_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-3164.2008.00694.x"},{"key":"e_1_2_6_6_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1939-1676.2009.0354.x"},{"key":"e_1_2_6_7_1","doi-asserted-by":"publisher","DOI":"10.1111\/vco.12160"},{"key":"e_1_2_6_8_1","doi-asserted-by":"publisher","DOI":"10.1111\/vco.12323"},{"key":"e_1_2_6_9_1","first-page":"931","article-title":"Intramuscular mast cell tumors in 7 dogs","volume":"58","author":"Robinson WP","year":"2017","journal-title":"Can Vet J"},{"key":"e_1_2_6_10_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1476-5829.2009.00200.x"},{"key":"e_1_2_6_11_1","doi-asserted-by":"publisher","DOI":"10.1111\/jvim.14601"},{"key":"e_1_2_6_12_1","doi-asserted-by":"publisher","DOI":"10.2460\/ajvr.78.11.1273"},{"key":"e_1_2_6_13_1","doi-asserted-by":"publisher","DOI":"10.1111\/vru.12336"},{"key":"e_1_2_6_14_1","doi-asserted-by":"publisher","DOI":"10.1177\/104063870501700305"},{"key":"e_1_2_6_15_1","doi-asserted-by":"publisher","DOI":"10.1177\/0300985810386469"},{"key":"e_1_2_6_16_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1476-5829.2009.00185.x"},{"key":"e_1_2_6_17_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jcpa.2014.07.004"},{"key":"e_1_2_6_18_1","doi-asserted-by":"publisher","DOI":"10.1002\/9781119421399.ch36"},{"key":"e_1_2_6_19_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0195-5616(90)50087-X"},{"key":"e_1_2_6_20_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1748-5827.2009.00732.x"},{"key":"e_1_2_6_21_1","doi-asserted-by":"publisher","DOI":"10.5326\/0380071"},{"key":"e_1_2_6_22_1","doi-asserted-by":"publisher","DOI":"10.5326\/JAAHA-MS-5557"},{"key":"e_1_2_6_23_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.tvjl.2012.11.018"},{"key":"e_1_2_6_24_1","doi-asserted-by":"publisher","DOI":"10.1111\/vco.12090"},{"key":"e_1_2_6_25_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1740-8261.2011.01839.x"},{"key":"e_1_2_6_26_1","doi-asserted-by":"publisher","DOI":"10.1111\/vru.12075"},{"key":"e_1_2_6_27_1","doi-asserted-by":"publisher","DOI":"10.1111\/vco.12012"},{"key":"e_1_2_6_28_1","doi-asserted-by":"publisher","DOI":"10.2460\/javma.228.1.91"},{"key":"e_1_2_6_29_1","doi-asserted-by":"publisher","DOI":"10.1177\/030098588402100503"},{"key":"e_1_2_6_30_1","doi-asserted-by":"publisher","DOI":"10.1177\/0300985814521638"},{"key":"e_1_2_6_31_1","doi-asserted-by":"publisher","DOI":"10.1080\/01652176.2005.9695186"},{"key":"e_1_2_6_32_1","doi-asserted-by":"publisher","DOI":"10.2460\/javma.2001.218.1120"},{"key":"e_1_2_6_33_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1476-5829.2006.00107.x"},{"key":"e_1_2_6_34_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1740-8261.2004.04054.x"},{"key":"e_1_2_6_35_1","first-page":"20","article-title":"Multiple distinct malignancies in dogs: 53 cases","volume":"46","author":"Rebhun RB","year":"2010","journal-title":"J Am Vet Med Assoc"}],"container-title":["Veterinary Radiology &amp;
