Significant changes in regional cerebral blood flow (rCBF) in the volume of interest were assessed in the posterior cingulate gyrus, precuneus and parietal cortices; the severity and extent of decreases in rCBF and the ratio of the extent of the decrease in rCBF to the decrease in whole-brain blood flow (rCBF ratio) were determined. &lt;i&gt;Results:&lt;\/i&gt; The severity of the decrease in rCBF in AD patients was significantly greater than in VD and FTD patients and controls. The extent of the decrease in rCBF in AD patients was significantly greater than in FTD patients and controls. The rCBF ratio in AD patients was higher than in VD and FTD patients and controls. &lt;i&gt;Conclusion:&lt;\/i&gt; The eZIS indices, especially the rCBF ratio, may be useful in establishing the differential diagnosis between early-stage AD and FTD or VD, but the differentiation of AD from VD + AD or DLB remains difficult.<\/jats:p>","DOI":"10.1159\/000180280","type":"journal-article","created":{"date-parts":[[2008,12,11]],"date-time":"2008-12-11T14:35:10Z","timestamp":1229006110000},"page":"547-555","source":"Crossref","is-referenced-by-count":24,"title":["Differentiation of Early-Stage Alzheimer\u2019s Disease from Other Types of Dementia Using Brain Perfusion Single Photon Emission Computed Tomography with Easy Z-Score Imaging System Analysis"],"prefix":"10.1159","volume":"26","author":[{"given":"M.","family":"Waragai","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"S.","family":"Mizumura","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"T.","family":"Yamada","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"H.","family":"Matsuda","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"127","published-online":{"date-parts":[[2008,12,10]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1006%2Fnimg.2000.0582"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1097%2F00006231-200401000-00010"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1007%2Fs00259-004-1491-3"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.2967%2Fjnumed.106.037218"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1016%2Fj.jns.2007.03.027"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1212%2FWNL.34.7.939"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.1212%2F01.wnl.0000187889.17253.b1"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.1016%2Fj.jns.2005.08.011"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.1212%2F01.wnl.0000219640.59984.a7"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.1002%2Fana.410420114"},{"key":"ref11","doi-asserted-by":"publisher","DOI":"10.1002%2Fana.1133"},{"key":"ref12","doi-asserted-by":"publisher","DOI":"10.1159%2F000085070"},{"key":"ref13","doi-asserted-by":"publisher","DOI":"10.1016%2Fj.neuroimage.2006.02.040"},{"key":"ref14","doi-asserted-by":"publisher","DOI":"10.1136%2Fjnnp.69.5.661"},{"key":"ref15","doi-asserted-by":"publisher","DOI":"10.1001%2Farchneurol.2007.29"},{"key":"ref16","doi-asserted-by":"publisher","DOI":"10.1093%2Fbrain%2Fawm228"}],"container-title":["Dementia and Geriatric Cognitive Disorders"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/180280","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/180280","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,24]],"date-time":"2025-04-24T00:18:48Z","timestamp":1745453928000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000180280"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2008]]},"references-count":16,"journal-issue":{"issue":"6","published-online":{"date-parts":[[2008,12,1]]}},"URL":"https:\/\/doi.org\/10.1159\/000180280","archive":["Portico"],"relation":{},"ISSN":["1420-8008","1421-9824"],"issn-type":[{"value":"1420-8008","type":"print"},{"value":"1421-9824","type":"electronic"}],"subject":[],"published":{"date-parts":[[2008]]}}}
