本文对15例CT扫描显示脑白质疏松症的病人进行血流动力学研究,并与9例正常对照组行对比性研究,旨在搞清慢性脑缺血或代谢低下与白质疏松症的关系。结果发现,脑白质疏松患者白质局部脑血流量(rCBF)与正常人组比较有显著性差异(P<0.05),而脑血容量(CBV)及CBF对乙酰唑胺的反应性却无显著性差异。大脑皮层rCBF、rCBV及rCBF对乙酰唑胺的反应性在病人组与正常对照组之间无显差异。
In this paper, 15 cases of leukoaraiosis patients with CT scan showed hemodynamic study, and 9 cases of normal control group were compared to study the relationship between chronic cerebral ischemia or hypometabolism and the relationship between white matter and osteoporosis. The results showed that there was a significant difference of white matter partial cerebral blood flow (rCBF) in patients with leukoaraiosis (P <0.05), while there was no significant difference in response to acetazolamide between cerebral blood volume (CBV) and CBF difference. The responsiveness of cerebral cortex rCBF, rCBV and rCBF to acetazolamide showed no significant difference between the patient group and the normal control group.
