Abstract

We measured the size of the endolymph using a newly proposed 10-min magnetic resonance (MR) imaging protocol and compared values with those of the previously reported 31- and 17-min protocols in 15 patients. Values for the 3 protocols did not differ significantly in either the cochlea or vestibule. Correlation among the 3 protocols was strong or relatively strong. Evaluation of endolymphatic hydrops is feasible using the newly proposed 10-min protocol.
