Twelve patients were studied before and after surgery. Prior to surgery, MRI abnormalities were found in all but one patient. After surgery, five patients had new abnormalities, mainly deep white-matter lesions (DWML). Postoperative P300 latency was significantly increased in six patients. P300 topographical distribution showed a shift from predominantly posterior cerebral regions to frontal regions in most patients. Postoperative P300 and MRI deficits were found in three of the five patients. One of the patients with marked MRI change (DWML in caudate nucleus) did not show P300 deficit.<\/jats:p>","DOI":"10.1177\/026765919300800407","type":"journal-article","created":{"date-parts":[[2007,11,26]],"date-time":"2007-11-26T20:11:10Z","timestamp":1196107870000},"page":"321-329","source":"Crossref","is-referenced-by-count":10,"title":["Magnetic resonance imaging and P300 (event-related auditory evoked potentials) in the assessment of postoperative cerebral injury following coronary artery bypass graft surgery"],"prefix":"10.1177","volume":"8","author":[{"given":"Istra","family":"Toner","sequence":"first","affiliation":[{"name":"Royal Postgraduate Medical School, Hammersmith Hospital"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shahnaz K","family":"Hamid","sequence":"additional","affiliation":[{"name":"Royal Postgraduate Medical School, Hammersmith Hospital"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Carol J","family":"Peden","sequence":"additional","affiliation":[{"name":"Royal Postgraduate Medical School, Hammersmith Hospital"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kenneth M","family":"Taylor","sequence":"additional","affiliation":[{"name":"Royal Postgraduate Medical School, Hammersmith Hospital"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Peter LC","family":"Smith","sequence":"additional","affiliation":[{"name":"Royal Postgraduate Medical School, Hammersmith Hospital"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Stanton P","family":"Newman","sequence":"additional","affiliation":[{"name":"Middlesex School of Medicine, London"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"D.","family":"Phil","sequence":"additional","affiliation":[{"name":"Middlesex School of Medicine, London"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[1993,7,1]]},"reference":[{"key":"atypb1","doi-asserted-by":"publisher","DOI":"10.1177\/026765918900400203"},{"key":"atypb2","doi-asserted-by":"publisher","DOI":"10.1177\/026765918900400202"},{"key":"atypb3","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(86)90938-4"},{"key":"atypb4","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(86)92871-0"},{"key":"atypb5","doi-asserted-by":"publisher","DOI":"10.1001\/archpedi.1990.02150270124041"},{"key":"atypb6","doi-asserted-by":"publisher","DOI":"10.1016\/0003-4975(92)91441-B"},{"key":"atypb7","volume-title":"Abstracts of the 10th annual scientific meeting and exhibition of the Society of Magnetic Resonance in Medicine","author":"De La Paz RL"},{"key":"atypb8","first-page":"324","volume":"40","author":"Schmidt R.","year":"1990","journal-title":"Neurology"},{"key":"atypb9","doi-asserted-by":"publisher","DOI":"10.1007\/BF00598610"},{"key":"atypb10","doi-asserted-by":"publisher","DOI":"10.1016\/0013-4694(80)90325-9"},{"key":"atypb11","doi-asserted-by":"publisher","DOI":"10.1161\/01.STR.17.3.410"},{"key":"atypb12","author":"Newman SP","year":"1993","journal-title":"Perfusion"},{"key":"atypb13","doi-asserted-by":"publisher","DOI":"10.1016\/0013-4694(92)90002-Y"},{"key":"atypb14","first-page":"179","volume":"77","author":"Polich J.","year":"1990","journal-title":"Clin Neurophysiol"},{"key":"atypb15","first-page":"717","volume":"41","author":"Engelhardt W.","year":"1992","journal-title":"Anaesthetist"},{"key":"atypb16","doi-asserted-by":"publisher","DOI":"10.1016\/0013-4694(80)90419-8"},{"key":"atypb17","first-page":"915","volume":"12","author":"Fazekas F.","year":"1991","journal-title":"AJNR"},{"key":"atypb18","unstructured":"Graham DG, Rierley JB Vascular disorders of the central nervous system.
