The angular trajectory of the vestibular aqueduct: evaluation using photon-counting CT [PDF]
Insights into ImagingThe 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 ...
