[Abstract] Objective: To compare 3 kinds of post-processing methods of magnetic resonance hydrography (MRH) technology (MPR, MIP and VR) in the usage of inner ear.Materials and Methods: Thirty-five patients with sensorineural hearing loss (SNHL) and 40 controls were recruited. High-resolution three-dimensional turbo spin echo T2WI (3D TSE T2WI) axial scanning and bilateral oblique sagittal scanning were performed in each subject with the data transmitted to the workstation for reconstruction by ViewForum. The data of inner ear was compared among different reconstruction modalities.Results: (1) Subtle anatomical structures of cochleovestibular nerve, facial nerve, and inner ear could be clearly shown in 80 ears of 40 adults. (2) The height of semicircular canals and diameter of upper and lateral semicircular canals were different between VR and MIP (P=0.001, P=0.000). (3) MPR was superior in displaying CN, FN, SVN and IVN; the scores of VR are higher than that of MPR and MIP in displaying the structure of V, PSC, SSC and HSC.Conclusion: Among the 3 methods of post-processing, MPR is the best to show the nerves of the labyrinth. VR is the best to display the details of inner ear diseases.
