脑梗塞患者SPECT容积测定与临床评分的相关性分析

The correlative analysis between volume measurement by SPECT and the clinical scoring in cerebral infarction

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。

PURPOSE To assess the reliability of the clinical scoring system by the volume measurement of cerebral infarc- tion with SPECT.METHODS The volume measurement of left and right brain in 20 healthy subjects was used as control.We studied the correlations between the volume of infarcted lesion measured by SPECT and two kinds of clinical scoring system in 31 patients who suffered from simple unilateral cerebral infarction.RESULTS The correlation coefficient between volume and score was 0.631～0.795(P<0.001).The coincidence rate was rather good.CONCLUSIONS SPECT study has objectively showed that these 2 kinds of clinical scoring system are quite reliable.
