Abstract
We describe a head tilt technique for use with CT angiography that reduces beam-hardening artifacts in patients with aneurysm clips, This simple maneu ver directs the artifacts away from pertinent anatomy, thus increasing the chances for diagnostic accuracy. No significant changes in the CT angiograp hic protocol are required, and the maneuver can easily be combined with oth er artifact-minimizing strategies.
