RT Journal Article SR Electronic T1 Reduction of Aneurysm Clip Artifacts on CT Angiograms: A Technical Note JF American Journal of Neuroradiology JO Am. J. Neuroradiol.

Taveras YR 1999 UL http://www.ajnr.org/content/20/4/694.abstract AB Summary: We describe a head tilt technique for use with CT angiography that reduces beam-hardening artifacts in patients with aneurysm clips. This simple maneuver directs the artifacts away from pertinent anatomy, thus increasing the chances for diagnostic accuracy. No significant changes in the CT angiographic protocol are required, and the maneuver can easily be combined with other artifact-minimizing strategies.
