1 A 3D-IR sequence depicts cochlear EH grade II (thin arrow) and vestibular EH grade II (thick arrow) on the right. A 3D-IR sequence depicts cochlear EH grade II (thin arrow) and vestibular EH grade II (thick arrow) on the right. EH is not visible on the corresponding 3D T2-weighted spatial and chemical-shift encoded excitation (SPACE) sequence. No EH on the normal left side is seen. Normal anatomy is shown at different levels (below the midmodiolar, midmodiolar, and above the midmodiolar sections) on the 3D-IR (0.8 mm) and 3D heavily T2-weighted SPACE (0.4 mm) sequence: interscalar septum (thin dashed arrow), anterior ampulla (thick dashed arrow), utricle/common crus (thick dotted arrow), and the lateral ampulla (arrowhead).
