Sagittal real-time bSSFP cine images of the cervical spine demonstrate multilevel spondylotic disease. With extension, there is impingement of the cord at the C5-C6 level due to anterior disc osteophyte complex and posterior thickened ligamentum flavum. There is hyperdynamic motion of the cord just distal to the cord impingement, likely due to accelerated CSF flow effects. With flexion, the cord impingement decreases.
Total cine clip time 0:35 with repeated flexion and extension motions showing the findings below:
0:05 – Extension
0:08 – Flexion
This is repeated through the course of the cine clip.
