CT artifacts

Last revised by Mohammad Taghi Niknejad on 30 Dec 2023

CT artifacts are common and can occur for various reasons. Knowledge of these artifacts is important because they can mimic pathology (e.g. partial volume artifact) or can degrade image quality to non-diagnostic levels.

CT artifacts can be classified according to the underlying cause of the artifact. 

Patient-based artifacts
Physics-based artifacts
Hardware-based artifacts
