Three Tesla MRI inner ear sequences in axial projection obtained from patient case II using the MRI HYDROPS sequence reconstructed over normal MRI sequences. Blue arrows point to cochlear endolymphatic hydrops that is radiologically present on both inner ears, but mainly on left side. Orange arrows point to vestibular endolymphatic hydrops, also present on both sides but again more relevant on the left side. With the HYDROPS sequence technique the normal endolymphatic volumes are not plotted and only when there is (radiologically) significant endolymphatic hydrops does this appear on HYDROPS sequences as black color volumes. For this figure the HYDROPS sequences images were automatically added to normal MRI structures to allow an easier identification of other nearby anatomical references of inner ear MRI axial images.

Tesla MRI examination of the inner ear using the HYDROPS MRI sequence: this sequence is based on the digital subtraction of images produced by the different time diffusion of gadolinium along the inner ear fluids. This MRI showed bilateral cochlear and vestibular endolymphatic hydrops with left side hydrops predominating, as can be observed in Figure 3.
