Objective: The aim of present study was to investigate images of 3D-T1 fast spin echo sequence in the endolymphatic space in patients with Menieres disease and low frequency sensorineural hearing loss Methodology: 30 patients divided into two groups were enrolled in this study.The first group included 20 patients who had Menieres disease.The second group included 10 patients who had low frequency sensorineural hearing loss.The patients underwent magnetic resonance imaging (MRI) after injection of gadolinium enhancement medium intratympanically The 3D-T1 fast spin echo sequence of magnetic resonance imaging is used.
