The purpose of this retrospective study was to describe characteristics observed using early postoperative magnetic resonance imaging in a group of dogs undergoing craniotomy for brain tumor removal. Two independent observers came to a consensus opinion for presence\/absence of the following MRI characteristics: residual tumor tissue; hemorrhage and ischemic lesions; abnormal enhancement (including the margins of the resection cavity, choroid plexus, meninges) and signal intensity changes on diffusion\u2010weighted imaging. Five dogs were included in the study, having had preoperative and early postoperative MRI acquired within four days after surgery. The most commonly observed characteristics were abnormal meningeal enhancement, linear enhancement at margins of the resection cavity, hemorrhage, and a thin rim of hyperintensity surrounding the resection cavity on diffusion\u2010weighted imaging. Residual tumor tissue was detected in one case of an enhancing tumor and in one case of a tumor containing areas of hemorrhage preoperatively. Residual tumor tissue was suspected but could not be confirmed when tumors were nonenhancing. Findings supported the use of early postoperative MRI as a method for detecting residual brain tumor tissue in dogs.<\/jats:p>","DOI":"10.1111\/vru.12248","type":"journal-article","created":{"date-parts":[[2015,3,10]],"date-time":"2015-03-10T07:58:24Z","timestamp":1425974304000},"page":"531-539","source":"Crossref","is-referenced-by-count":11,"title":["EARLY POSTOPERATIVE MAGNETIC RESONANCE IMAGING FINDINGS IN FIVE DOGS WITH CONFIRMED AND SUSPECTED BRAIN TUMORS"],"prefix":"10.1111","volume":"56","author":[{"given":"Kathleen Ella","family":"Chow","sequence":"first","affiliation":[{"name":"University of Melbourne Veterinary Hospital Radiology Department  Melbourne Victoria Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dayle","family":"Tyrrell","sequence":"additional","affiliation":[{"name":"University of Melbourne Veterinary Hospital Radiology Department  Melbourne Victoria Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sam Nicholas","family":"Long","sequence":"additional","affiliation":[{"name":"University of Melbourne Veterinary Hospital Radiology Department  Melbourne Victoria Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2015,3,10]]},"reference":[{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.1002\/ana.410170607"},{"key":"e_1_2_6_3_1","first-page":"13","article-title":"Postoperative imaging after brain tumor resection","volume":"88","author":"Warmuth\u2010Metz M","year":"2003","journal-title":"Acta Neurochir Suppl"},{"key":"e_1_2_6_4_1","doi-asserted-by":"publisher","DOI":"10.1227\/00006123-199401000-00008"},{"key":"e_1_2_6_5_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1740-8261.2000.tb01866.x"},{"key":"e_1_2_6_6_1","doi-asserted-by":"publisher","DOI":"10.1148\/radiology.139.2.7220887"},{"key":"e_1_2_6_7_1","doi-asserted-by":"publisher","DOI":"10.1007\/s003300000800"},{"key":"e_1_2_6_8_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1740-8261.2006.00120.x"},{"key":"e_1_2_6_9_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1740-8261.2012.01944.x"},{"key":"e_1_2_6_10_1","doi-asserted-by":"publisher","DOI":"10.1148\/rg.325115760"},{"key":"e_1_2_6_11_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.crad.2004.01.019"},{"key":"e_1_2_6_12_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00330-011-2081-y"},{"issue":"8","key":"e_1_2_6_13_1","first-page":"1547","article-title":"Surgically induced intracranial contrast enhancement: potential source of diagnostic error in intraoperative MR imaging","volume":"20","author":"Knauth M","year":"1999","journal-title":"AJNR Am J Neuroradiol"},{"key":"e_1_2_6_14_1","doi-asserted-by":"publisher","DOI":"10.1148\/radiology.204.3.9280269"},{"key":"e_1_2_6_15_1","doi-asserted-by":"publisher","DOI":"10.1148\/radiology.174.1.2294579"},{"key":"e_1_2_6_16_1","doi-asserted-by":"publisher","DOI":"10.1148\/radiology.174.1.2294578"},{"key":"e_1_2_6_17_1","doi-asserted-by":"publisher","DOI":"10.1227\/00006123-199412000-00007"},{"key":"e_1_2_6_18_1","doi-asserted-by":"publisher","DOI":"10.1007\/s10143-010-0304-3"},{"key":"e_1_2_6_19_1","doi-asserted-by":"publisher","DOI":"10.1212\/01.wnl.0000242894.21705.3c"},{"key":"e_1_2_6_20_1","doi-asserted-by":"publisher","DOI":"10.1227\/01.NEU.0000219218.43128.FC"},{"key":"e_1_2_6_21_1","doi-asserted-by":"publisher","DOI":"10.3171\/jns.2005.103.3.0428"},{"key":"e_1_2_6_22_1","first-page":"115","article-title":"Evaluation of parenchymal changes at the operation site with early postoperative brain diffusion\u2010weighted magnetic resonance imaging","volume":"12","author":"Ozt\u00fcrk A","year":"2006","journal-title":"Diagn Interv Radiol"},{"key":"e_1_2_6_23_1","first-page":"1967","article-title":"Radiation necrosis versus glioma recurrence: conventional MR imaging clues to diagnosis","volume":"26","author":"Mullins ME","year":"2005","journal-title":"Am J Neuroradiol"}],"container-title":["Veterinary Radiology &amp;
