Vestibular aqueduct grading on the Pöschl planes
Vestibular aqueduct grading on the Pöschl planes on 3D sampling perfection with application-optimized contrasts using different flip angle evolutions (3D-SPACE). (a) Grade A with a continuous vestibular aqueduct (arrow). (b) Grade B with a discontinuous vestibular aqueduct (arrow). (c) Grade C with a no visible vestibular aqueduct. Note: The Pöschl projection is used in imaging the temporal bone; the plane of projection is perpendicular to the long axis of the temporal bone. (Source: Xia K, Lei P, Liu Y, et al.
