大脑中动脉高密度征 (ＨＭＣＡＳ)是大脑中动脉(ＭＣＡ)血栓的标志 ,其特异性接近 10 0 %。以往的研究表明 ,发病初几小时内ＨＭＣＡＳ检出率较高。本研究旨在明确ＨＭＣＡＳ的检出率 ,初始神经病学表现的严重程度与早期ＣＴ脑实质缺血性改变的联系 ,以及与之有关的临床结果和
Middle Cerebral Artery High Density Syndrome (HMCAS) is a marker of middle cerebral artery (MCA) thrombus with a specificity of nearly 100%. Previous studies have shown that the detection rate of HMCAS is high in the early hours of onset. The purpose of this study was to determine the association between the prevalence of HMCAS, the severity of initial neurological manifestations, and early ischemic changes in CT brain and the clinical outcomes associated with them
