Both intratympanic (IT-method) and intravenous (IV-method) administration of gadodiamide are used to detect endolymphatic hydrops. The purpose of our study was to comprehensively compare the image quality of the two methods. By qualitative and quantitative comparison, the IV-method can be used as an alternative to the IT-method in future clinical applications.
