Abstract:
Although measurement of cerebral blood flow by radioactive - isotope method became popular, there is still no report of study on the cerebral blood flow in Korea. Auther studied the regional cerebral blood flow in 28 normal Korean adults and and 76 patients including 14 cases of essential hypertension, 11 cases of heart diseases (coronary artery disease, valvular diseases and A-V block), 14 cases of brain diseases(cerebral thrombosis and cerebral insufficiency), 22 cases of head trauma and 15 cases of miscellaneous medical diseases. The regional cerebral blood flow was measured by intravenous in jection of (99m)Tc-DTPA 15-20Ci and by taking serial cerebral angiograms with CGR Gamma Tome 7000 and was analized by computer Imac 7310. The results were as follows: 1) The average regional cerebral blood flow of normal Korean adult was 50.0+/-5.89mg/100g /min. with range of 41-60ml/100g/min. 2) In most cases of essential hypertension the regional cerebral blood flow was within normal limit except rare case which was considered to have impaired autoregulation of cerebral blood flow. 3) In patients with myocardial infarction, valvular heart diseases with congestive heart failure and complete A-V block, there was markedly reduced cerebral blood flow. The reduced cerebral blood flow increased after the improvement of congestive heart failure and after the implantation of pacemaker. 4) In patients with cerebral thrombosis with infarction and cerebral insufficiency with symptoms of dizziness, headache or blurred vision, the cerebral blood flow was considerably reduced. However in acute encephalits the cerebral blood flow was increased. The measurement of cerebral blood flow by radioactiveisotope method is considered to be accurate, easy and useful clinical test to evaluate brain diseases and function.
