[Intl_DxMedPhys] CT artifact

[Stephanie M. Leon]

Hi all,

I have an odd CT artifact that a radiologist brought to my attention. The top image has bright gyri on the right cerebrum.  The 2nd image shows the gyri okay in the left cerebrum, but very bright in the cerebellum.  The cerebellum is also very bright in the 3rd image.

This is from a Canon Aquilion Prime SP, helical acquisition, AIDR 3D recon and FC26 kernel. It is apparent in the axial images too, just a bit harder to see. The patient received an MRI to follow up, which was normal.

Any ideas??
