Results
3 out of the 4 patients had both thickening of the vessel wall on curved MPR reconstructions and markedly reduced attenuation(>250HU) of the affected vertebral artery vs the unaffected side at the level of the occipital condyle on the 45keV mono energy reconstruction.
1 of the 4 patients had sections of occlusion/loss of contrast opacification along the affected vertebral artery that precluded vessel tracking to allow a curved MPR reconstruction but also demonstrated marked attenuation on the 45keV mono energy reconstruction at the level of the occipital condyle.
