The physiological range of radioisotope (RI) transferred from the CSF to the nasal secretions was observed in 17 subjects without CSF rhinorrhea. A combination of RI cisternography and insertion of cotton pledgets in the nose was used in order to detect the RI transfer in the nasal secretion. The RI ratio was calculated, and those of the 17 subjects were less than 0.3. This is likely to be the normal physiological range of RI transfer.
在17例无脑脊液鼻漏的受试者中观察了放射性同位素（RI）从脑脊液转移至鼻分泌物的生理范围。采用RI脑池造影和鼻腔内插入棉拭子相结合的方法来检测鼻分泌物中的RI转移情况。计算RI比值，17例受试者的RI比值均小于0.3。这可能是RI转移的正常生理范围。
