Keywords: Head & Neck/ENT, Diffusion/other diffusion imaging techniques, Benign paroxysmal positional vertigo, turbo spin-echo diffusion weighted imagingThis study explored the feasibility of TSE-DWI in inner ear and determined the diagnostic accuracy and interobserver performance of TSE-DWI in BPPV. The method is to evaluate the difference of ADC values between benign paroxysmal positional vertigo (BPPV) patients and healthy controls. Our research shows that The ADC values of semicircular canal in the BPPV patients (affected side) were higher than that of the contralateral ear. Moderate diagnostic accuracy of DWI was seen in the diagnosis of BPPV. Therefore, we consider that the TSE-DWI derived ADC value may represent promising novel imaging markers of inner ear disease.
