The optimization of 64-MDCT brain and neck angiography / 中华全科医师杂志

Sixty patients who underwent brain and neck CT angiograpby (CTA) were randomly divided into two groups: conventional protocol group and optimizing protocol group with 30 in each. The images were evaluated by two radiologists independently. The images of optimizing group avoided the artifact disturbance of the brachiocephalic vein effectively and greatly improved the imaging quality of arteria carotis communis and arteria vertebralis initial segment. Compared with the conventional group the differences were statistically significuat(P <0.05). The optimization of 64-MDCT brain and neck CTA is feasible and effective.
