设置窗位32Hu和窗宽8Hu并适当调节,以加强灰质白质对比,能更好显示急性(小于6h)大脑中动脉卒中的缺血性低密度灶(在工作站上调节)。标准的观察参数对检出卒中的敏感度和特异度是57%和100%,而使用本法可使敏感度升为71%而不影响特异度CT平扫调整窗宽窗位改善急性脑卒中的检
Setting window level 32Hu and window width 8Hu with appropriate adjustments to enhance gray matter white matter contrast and better display ischemic low-density foci (adjusted on the workstation) for acute (less than 6h) middle cerebral artery stroke. The sensitivity and specificity of standard observational parameters for detecting stroke were 57% and 100%, whereas using this method resulted in a sensitivity increase of 71% without affecting the specificity.
