A study on the dynamic exploration of the auditory pathway is presented, in which technetium-99m hexamethylpropylene amine oxime single-photon emission computed tomography (SPET) was used in volunteers with normal hearing. Changes in 99mTc-HMPAO distribution were calculated using a region of interest/whole-brain count ratio. The results showed a temporal perfusion increment of 17% (right) and 19% (left) during tonal supraliminar stimulation, which was significantly different from the control ROI. Sensitivity tests for the method were requested before any clinical application.
本文介绍了一项关于听觉通路动态探索的研究，该研究在听力正常的志愿者中使用了锝-99m六甲基丙烯胺肟单光子发射计算机断层扫描（SPET）。使用感兴趣区/全脑计数比计算99mTc-HMPAO分布的变化。结果显示，在音调阈上刺激期间，右侧颞部灌注增加17%，左侧增加19%，这与对照感兴趣区有显著差异。在进行任何临床应用之前，需要对该方法进行敏感性测试。
