Abstract
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.
摘要
我们描述了一种用于CT血管造影的头部倾斜技术，该技术可减少患有动脉瘤夹的患者中的束硬化伪影。这种简单的操作可将伪影引导至远离相关解剖结构的位置，从而提高诊断准确性的几率。无需对CT血管造影方案进行重大更改，并且该操作可轻松与其他减少伪影的策略相结合。
