Motivation: The optimal VENC setting for the 3D PC imaging of radial/ulnar arteries remains unclear.
Goal(s): We aimed to investigate the optimal VENC setting of radial/ulnar arteries.
Approach: All patients underwent MRA imaging using the 3D PC method with three different VENC settings (15, 30, and 45). The SNR of radial/ulnar arteries was calculated. The differences in mean SNR were assessed using Kruskal–Wallis analysis with post hoc pairwise comparisons. Five cerebrovascular treatment specialists assessed the clarity and visual quality of the radial/ulnar artery imaging.
Results: The SNR and average degree of preference were high for a VENC setting of 15.
Impact: A VENC setting of 15 is appropriate for MRA imaging of radial/ulnar arteries using the 3D PC method, allowing preoperative vascular evaluation in transradial/transulnar neurointervention. However, the VENC settings for younger patients should be determined after consultation with clinicians.
