Ultrahigh frequency acoustic stimulation-a pet analysis pre and post stimulation in six tinnitus patients.

Abstract

PET of brain neuro-imaging was performed in six tinnitus patients pre and post ultrahigh frequency stimulation attempting tinnitus relief. Significant has been findings of alterations in metabolism as identified by perfusion asymmetries in multiple regions of interest in brain (primary auditory cortex, medial temporal lobe system, frontal, parietal lobes, and cerebellum. Statistical significance was identified for the cerebellum. Significant correlation identified/established between PET metabolic changes in primary auditory cortex, minimal masking levels and auditory thresholds. Conclusion is of a positive effect in all patients studied of ultrahigh frequency stimulation as established by correlation of PET findings pre and post stimulation with the varying degrees of tinnitus relief as reported by the patients.
