鼻腔粘膜纤毛传输速率(MTR)的研究始自1830年,起初是直接观察某种物质在鼻粘膜上的运动速率,嗣后有糖精法,1965年Proctor等首次报道用碘—MAA记录其沿鼻道的传输时间,方法简单、便宜、无创,但较粗糙,自~(99m)锝被用作扫描剂后才为MTR测定提供了定量数据。作者采用~(99m)锝作示踪剂测定正常人及某些鼻病患者的MTR,共获38例(不吸烟健康人 Nasal mucociliary transfer rate (MTR) study began in 1830, was the first direct observation of a substance in the nasal mucosa of the rate of movement, followed by the saccharin method, Proctor, etc. for the first time reported in 1965 with iodine-MAA along the nasal passages The delivery time was simple, inexpensive, noninvasive, and less rough, providing quantitative data for the MTR assay since ~ (99m) technetium was used as a scintillator. The authors used ~ (99m) technetium as a tracer for the determination of MTR in normal and some rhinosinusitis patients, a total of 38 (non-smoking healthy people
