Positron emission tomography (PET) imaging was used to evaluate the brain's response to auditory stimulation, including speech. Five cases of adults illustrate the utility of PET to illuminate auditory processing with cochlear or brainstem implants. Subjects showed varying degrees of success in processing speech, which was reflected in the resulting PET images. Functional speech processing was associated with activation in areas classically associated with speech processing. In one patient who did not achieve functional speech processing, activation in frontal regions suggests that the subject used other cognitive strategies to assist auditory processing.
As a result of this activity, the participant will be introduced to the principles of PET and the application of this technology to deaf patients who have received an implanted auditory prosthesis.
正电子发射断层扫描（PET）成像用于评估大脑对听觉刺激（包括言语）的反应。5例成人病例说明了PET在阐明人工耳蜗或脑干植入物听觉处理方面的作用。受试者在言语处理方面表现出不同程度的成功，这在PET图像中得到了体现。功能性言语处理与经典言语处理区域的激活有关。在一名未实现功能性言语处理的患者中，额叶区域的激活表明该受试者使用了其他认知策略来辅助听觉处理。
通过本活动，参与者将了解PET的原理以及该技术在接受植入式听觉假体的聋人患者中的应用。
