Endolymphatic hydrops of Meniere's disease has been evaluated by intratympanic (IT) or intravenous (IV) Gd injection. We have developed a novel method to image the patient who recieved IT in one ear and IV simultaneously. Proposed HYDROPS2 method can replace 3D-real IR method currently used in most institutions.
