Normal Values of Cerebral Blood Flow in Korean Determined by Tc-99m DTPA

Technetium 99m DTPA를 이용(利用)한 정상(正常) 한국인(韓國人)의 뇌혈류량(腦血流量) 측정(測定)

There are several methods for measurement of cerebral blood flow. A method using Tc-99m DTPA which was injected via antecubital vein and monitored extracranially with gamma camera is described here. In this method, the brain scan and CBF mesurement were performed with scan and CBF were usually studied separately. The results were as follow: 1) Total candidates were 53, male 34 and female 19, who have no evidence of neurologic, cardiac or kidney problems. 2) By this method, the normal CBF of Korean was $54.12{\pm}6.49ml/min/100g$ of brain tissue. 3) The CBF of male was $54.06{\pm}5.9ml/min/100g$ of brain tissue, female was $54.89{\pm}6.51ml/min/100g$, so there was no definite sex difference. 4) The CBF under 10 years of age was $54.12{\pm}2.5ml/min/100g$, $11\sim20years$ of age was $52.33{\pm}6.1ml/min/100g$, $21\sim60years$ of age was $52.86{\pm}5.06ml/min/100g$, and over 61years of age was $55.43{\pm}4.84ml/min/100g$, so there was no significant difference of CBF by age.
