| Research Abstract |
To develop less invasive and robust objective diagnostic method for Meniere’s disease, we developed various methods as follows; custom built dedicated four channel coil which has 2 times SNR compared to commercial coil. Optimal timing of imaging after iv-Gd was 3.5h-4.5h. We developed positive endolymph image (PEI). For the image processing, we developed a method to separately visualize bone, endolymph and perilymph on a single image. We subtractPEI from PPI, resulting in the HYDROPS image. We also developed HYDROPS2 image etc by the subtraction of T2 from PPI. Additionally, we succeeded the semi-quantification of endolymph size by iv-Gd.
