The lateral radiograph of the cervical spine shows anterolisthesis of C5 over C6 and one of the inferior articular facet of C5 is slipped infront and is lying atop of the superior articular facet of C6 (so called perched facet).
The T2w sagittal image show minimal synovial fluid posterior to the right superior facet of C6.
The GRE sagittal image shows normal bright signal in the left vertebral artery, while the bright signal in right vertebral artery is lost s/o thrombosis.
The T2w axial image shows loss of signal void in the right vertebral artery s/o thrombosis.
