Endolymphatic Hydrops (EH) on MRI
EH is the distension of the endolymphatic space of the inner ears and is considered the hallmark of Menière's disease.
EH is the distension of the endolymphatic space of the inner ears and is considered the hallmark of Menière's disease.
Delayed postcontrast imaging (optimized 3D-FLAIR):
Gd reachs the perilymph but not the endolymph
Gd reachs the perilymph but not the endolymph
EH MRI Protocol
Cochlear EH Grading
Vestibular EH Grading
Tip 1: read the 3D-FLAIR sequence together with a heavily T2-weighted sequence to help differentiate the EH (arrows) and the surrounding bone.
Tip 2: be aware of the expected regions that accumulate Gd after 4h of IV injection. #NeuroRad #hnrad #otolaryngology
