Direct Visualization of Tracer Permeation into the Endolymph in Human Patients Using MR Imaging
CONCLUSION: This study provides the first in vivo systematic confirmation of GBCA entering the endolymph following intravenous administration. Notably, endolymph uptake peaked at 24h, significantly later than perilymph and CSF. The lack of a link between endolymph contrast and both perilymph and age suggests distinct uptake mechanisms. These findings shed light on inner ear fluid dynamics and their potential implications in Ménière's disease and other inner ear disorders.PMID:38569839 | DOI:10.2463/mrms.mp.2024-0011
