Impact of post-processing on image quality and metal artifact reduction. a Non-enhanced CT and b CT angiography with pronounced scattering artifacts of a coil-treated anterior communicating artery aneurysm. c CT angiography with metal artifact reduction (MAR) and model-based iterative reconstruction (MBIR) providing substantial artifact reduction. d Subtraction CT angiography with MAR and MBIR filtering providing further artifact reduction and resulting in adequate image quality for diagnostic evaluation
