目前CT对急性脑卒中的诊断发挥着巨大的作用,但脑梗死发病24h内CT改变多不明显,不利于早期诊断。本文通过对100例患者进行回顾性研究发现急性大脑中动脉(MCA)梗死的早期CT征象对预测梗死部位和程度有很大的价值。 方法 从美国贝瑟肯医院神经内科1989年～1990年收治的562例患者中剔除脑出血、复发性脑梗死,TIA等,选出100例首次发作MCA缺血症状并在14h内入院者作为研究对象;其中男性48例,女性52例,平均年龄70.8岁。所有对象均有入院前和后来显
At present, CT plays a huge role in the diagnosis of acute stroke. However, CT changes within 24 hours after onset of cerebral infarction are not obvious, which is not conducive to early diagnosis. This retrospective study of 100 patients found that early CT signs of acute middle cerebral artery (MCA) infarction have great value in predicting the site and extent of infarction. Methods One hundred and fifty patients with first episode of MCA ischemia were enrolled in this study from 562 patients admitted to Besser Hospital in the United States from 1989 to 1990 who were excluded from cerebral hemorrhage, recurrent cerebral infarction and TIA. Objects; including 48 males and 52 females, with an average age of 70.8 years. All subjects were admitted before and after the show
