1、肺灌注斷層顯像和平面顯像對肺栓塞診斷的價值研究［摘耍］冃的:評價肺灌注斷層顯像對肺栓塞(PE)的診斷價值。方法:對76例確診為PE的患者進行肺灌注斷層和平而顯像，次II行肺通氣顯像，顯像結(jié)果和CT肺動脈造影(CTPA)進行對比分析。結(jié)果:在76例PE患者中，肺灌注斷層顯像陽性72例，檢出率為94.7%;肺灌注平面顯像陽性64例,檢出率為84.2%,兩種方法PE檢出率差異有統(tǒng)計學(xué)意義(P<0.05)°76例患者中,CTPA顯示受累肺段為329個，肺灌注斷層顯像示314個肺段陽性，肺灌注斷層顯像與CTPA的符合率為95.4%;肺灌注平面顯
2、像示261個肺段陽性,兩者符合率為79.3%,兩符合率比較，爰異有高度統(tǒng)計學(xué)意義(P〈0.01)o結(jié)論:肺灌注斷層顯像能顯著提高對PE的診斷率，可作為診斷PE的常規(guī)篩查方法。［關(guān)鍵詞］肺栓塞;核素肺灌注顯像;CTPA［中圖分類號］R445?5［文獻標識碼］B［文章編號］1673-7210(2010)02(a)-067-02TheroleoflungperfusiontomographyinthediagnosisofpulmonaryembolismincomparisonwithplanarperfusionimagingIJUYa
