Our purpose was to describe the magnetic resonance (MR) imaging features of histologically confirmed canine intracranial astrocytomas and oligodendrogliomas and to examine for MR features that differentiate these tumor types. Thirty animals with confirmed astrocytoma (14) or oligodendroglioma (16) were studied. All oligodendrogliomas and 12 astrocytomas were located in the cerebrum or thalamus, with the remainder of astrocytomas in the cerebellum or caudal brainstem. Most (27\/30) tumors were associated with both gray and white matter. The signal characteristics of both tumor types were hypointense on T1\u2010weighted images (12 each) and hyperintense on T2\u2010weighted images (11\/14 astrocytomas, 12\/16 oligodendrogliomas). For astrocytomas and oligodendrogliomas, respectively, common findings were contrast enhancement (10\/13, 11\/15), ring\u2010like contrast enhancement (6\/10, 9\/11), cystic regions within the mass (7\/14, 12\/16), and hemorrhage (4\/14, 6\/16). Oligodendrogliomas were significantly more likely to contact the brain surface (meninges) than astrocytomas (14\/16, 7\/14, respectively,\n                    <jats:italic>P<\/jats:italic>\n                    =0.046). Contact with the lateral ventricle was the most common finding, occurring in 13\/14 astrocytomas and 14\/16 oligodendrogliomas. No MR features were identified that reliably distinguished between these two tumor types. Contrast enhancement was more common in high\u2010grade tumors (III or IV) than low\u2010grade tumors (II,\n                    <jats:italic>P<\/jats:italic>\n                    =0.008).\n                  <\/jats:p>","DOI":"10.1111\/j.1740-8261.2010.01758.x","type":"journal-article","created":{"date-parts":[[2010,11,3]],"date-time":"2010-11-03T00:33:23Z","timestamp":1288744403000},"page":"132-141","source":"Crossref","is-referenced-by-count":102,"title":["MAGNETIC RESONANCE IMAGING FEATURES OF INTRACRANIAL ASTROCYTOMAS AND OLIGODENDROGLIOMAS IN DOGS"],"prefix":"10.1111","volume":"52","author":[{"given":"BENJAMIN D.","family":"YOUNG","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"JONATHAN M.","family":"LEVINE","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"BRIAN F.","family":"PORTER","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"ANNIE V.","family":"CHEN\u2010ALLEN","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"JOHN H.","family":"ROSSMEISL","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"SIMON R.","family":"PLATT","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"MARC","family":"KENT","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"GEOFFREY T.","family":"FOSGATE","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"SCOTT J.","family":"SCHATZBERG","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2010,11,2]]},"reference":[{"key":"e_1_2_6_2_2","first-page":"669","article-title":"Canine intracranial primary neoplasia","volume":"20","author":"Snyder JM","year":"2006","journal-title":"173 cases (1986\u20132003)"},{"key":"e_1_2_6_3_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00401-007-0243-4"},{"key":"e_1_2_6_4_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1939-1676.1991.tb00952.x"},{"key":"e_1_2_6_5_2","doi-asserted-by":"publisher","DOI":"10.3171\/jns.2006.105.1.6"},{"key":"e_1_2_6_6_2","first-page":"428","article-title":"Oligodendrogliomas","volume":"76","author":"Shaw EG","year":"1992","journal-title":"the Mayo Clinic experience"},{"key":"e_1_2_6_7_2","doi-asserted-by":"publisher","DOI":"10.1093\/jnen\/64.6.479"},{"key":"e_1_2_6_8_2","first-page":"737","article-title":"Clinical signs, magnetic resonance imaging findings and survival in dogs with intracranial meningiomas and glial cell tumors","volume":"23","author":"De Stefani A","year":"2009","journal-title":"J Vet Intern Med"},{"key":"e_1_2_6_9_2","first-page":"708","article-title":"Effects of palliative pharmacotherapy on survival and quality of life in 50 dogs with primary intracranial neoplasms","volume":"23","author":"Rossmeisl J","year":"2009","journal-title":"J Vet Intern Med"},{"key":"e_1_2_6_10_2","first-page":"445","volume-title":"Magnetic resonance imaging of the brain and spine","author":"Jayaraman MV","year":"2009"},{"key":"e_1_2_6_11_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1939-1676.1997.tb00094.x"},{"key":"e_1_2_6_12_2","doi-asserted-by":"publisher","DOI":"10.1016\/S1096-2867(99)80009-7"},{"key":"e_1_2_6_13_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.tvjl.2009.10.011"},{"key":"e_1_2_6_14_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1740-8261.1996.tb00807.x"},{"key":"e_1_2_6_15_2","first-page":"555","article-title":"Diffuse cerebral and leptomeningeal astrocytoma in dogs","volume":"14","author":"Kraft SL","year":"1990","journal-title":"MR features"},{"key":"e_1_2_6_16_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1740-8261.2005.00069.x"},{"key":"e_1_2_6_17_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1740-8261.2008.00336.x"},{"key":"e_1_2_6_18_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.tvjl.2005.05.012"},{"key":"e_1_2_6_19_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1740-8261.1997.tb00866.x"},{"key":"e_1_2_6_20_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1939-1676.2009.0306.x"},{"key":"e_1_2_6_21_2","unstructured":"KoestnerA BilzerT FatzerR SchulmanFY SummersBA Van WinkleTJ.Histologic classification of tumors of the nervous system of domestic animals Vol. 5 2nd ed.
