本文报告了用脑血流图描记法,测定了50例40至60岁的脑动脉硬化病人及正常人100例,观察了脑血管弹性、充盈程度、血管紧张度等指标。结果见到:①波形除6例近似正常外,其余44例均属异常波形,三峰递增波在异常波形中的比例最大占28%、平顶波占16%,圆顶波占14%,正弦波占16%、三角波占8%、低平波占6%。②上升时间(流入时间)延长,平均值为0.24秒(正常值为0.10～0.22秒)。③波 In this paper, 100 cases of cerebral arteriosclerosis in 40-60 years old and 100 normal persons were measured by cerebral blood flow mapping. The indexes of cerebral vascular elasticity, filling degree and vascular tone were observed. The results showed that: ① The waveform was abnormal except for 6 cases, and the other 44 cases were abnormal waveform. The largest proportion of the increasing wave in the three peaks was 28%, the flattened wave accounted for 16%, the dome-shaped wave accounted for 14% Waves accounted for 16%, triangle waves accounted for 8%, low flat wave accounted for 6%. ② Rise time (inflow time) extended, the average value of 0.24 seconds (normal 0.10 to 0.22 seconds). ③ wave
