B, Single frame from sagittal HASTE imaging series of the same temporomandibular joint. In both studies, the articular eminence (AE), condyle (C), and articular disk (arrowheads) are demonstrated.

A, Closed- and open-mouthed static sagittal oblique proton-attenuation images and (B) selected frames from dynamic sagittal HASTE image series, acquired from the same TMJ. Anteriorly displaced disk material (arrowheads) is more clearly identified on the dynamic series, with reduction of material seen by the 3rd image.
