应用CBA，CV-300型脑血管动力学检测仪对脑血管病及其病因病进行检查，发现阳性率均在92.5％，98.46％，其脑血管动力学参数（CVDI）的临床意义特点：脑出血和脑梗塞在急性期均出现明显异常，脑出血的CP增高、脑梗塞的动脉硬化发生率为其特点。同CT对比，CVDI异常与CT定位大多数相一致，且比CT出现得早，存在早期诊断价值，高血压糖尿病的CVDI特点为双侧对称性异常，出现明显不对称性异常，可视为卒中前改变。
The cerebrovascular disease and its etiological disease were examined by CBA and CV-300 cerebral angiography. The positive rates were 92.5% and 98.46% respectively. The clinical significance of cerebrovascular dynamics parameters (CVDI) Bleeding and cerebral infarction in the acute phase showed significant abnormalities, cerebral hemorrhage increased CP, atherosclerosis incidence of cerebral infarction for its characteristics. Compared with CT, CVDI anomaly is consistent with most of the CT location, and earlier than CT, there is early diagnostic value, CVDI characteristics of hypertensive diabetes mellitus are bilateral symmetry abnormalities, obvious asymmetry abnormalities can be considered as stroke Change before.
