The angular trajectory of the vestibular aqueduct (ATVA) has been proposed as a radiographic marker for developmental endotypes of Menière's disease. Current ATVA measurements rely on software-based proxies because the proximal vestibular aqueduct is often below the spatial resolution of conventional CT....

Discussion
Signed responses from readers of the wire.
Photon-counting CT shows promise for measuring vestibular aqueduct geometry, but this is a technical evaluation study; clinicians should not yet change imaging protocols or Menière's disease subtyping practice.
Precise radiographic characterization of vestibular aqueduct morphology using photon-counting CT could eventually enable objective subtyping of Menière's disease, supporting more personalized treatment strategies.
