通过 SPECT 对脑梗塞的容积测定,判断临床评分的可靠性。以20例正常人大脑左右容积测定结果作对照,对31例单纯性一侧脑梗塞患者用 SPECT 测定梗塞灶的容积,并与国内外两种临床评分法进行相关性分析。结果梗塞灶容积值及梗塞灶占大脑总容积比值与国内外临床评分值的相关系数分别为0.631、0.666和0.792、0.795(P 均<0.001)。表明目前采用的临床评分法基本可信。
The volume of cerebral infarction volume measured by SPECT to determine the reliability of clinical scores. The volume of left and right brain was measured in 20 normal subjects as control. The volume of infarction area was measured by SPECT in 31 patients with simple unilateral cerebral infarction. Correlation analysis was made between the two clinical scores at home and abroad. Results The correlation coefficients of infarct volume and infarct volume to total brain volume were 0.631,0.666 and 0.792,0.795 respectively (all P <0.001). This shows that the current clinical scoring method is basically credible.
