AND PURPOSE: Vestibular atelectasis (VA) is a histologically defined collapse of the membranous labyrinth, often accompanied by dense basophilic deposits. While delayed postcontrast 3D-FLAIR imaging allows indirect visualization of VA, no in vivo correlate of the basophilic deposits has been reported....

Signed responses from readers of the wire.
No immediate practice change; this is early-stage imaging biomarker work requiring prospective validation before it can guide vestibular diagnosis in routine clinical settings.
If validated, in vivo MRI detection of ampullary T2 hypointensity could offer the first non-invasive way to diagnose vestibular atelectasis, potentially transforming workup for unexplained vestibular disorders.
- 01Ampullary T2 hypointensity on MRI is proposed as an in vivo imaging biomarker for vestibular atelectasis.
- 02Vestibular atelectasis (membranous labyrinth collapse) has historically only been confirmed at post-mortem histology.
- 03The study establishes a potential bridge between a radiological finding and a previously histology-only diagnosis.
- 04Findings are published in Otology & Neurotology, a peer-reviewed specialty journal.
- 05Prospective studies linking this MRI marker to clinical vestibular symptoms and outcomes are still needed.
Ampullary T2 hypointensity on MRI can be detected in vivo and serves as a marker of vestibular atelectasis.
