Partial volume averaging (CT artifact)

Partial volume artifact occurs when tissues of widely different absorption are encompassed on the same CT voxel producing a beam attenuation proportional to the average value of these tissues. 

The last generation of CT scanners and its reduction in the volume of a voxel has substantially reduced the occurrence of this artifact.
