VERTEBRAL ARTERY OCCULSION
- With spinal trauma its essential to look at the signal of the vertebral arteries as there can be dissection.
- In most cases we don’t do a routine MRA so being able to spot a dissection on the standard scans is very important to look for an occluded vertebral artery that would indicate underlying dissection.
- Normal vertebral arteries should be low signal (Green arrow) due to the blood flow resulting in a flow void.
- In this case there is increased signal in the right vertebral artery (Pink arrow) which is abnormal.
- The patient had a spinal fracture and dissection of the vertebral artery resulting in occlusion.
Absent flow void in the right vertebral artery (Pink arrow).
