4D flow shows great potential in neurovascular disorders such as stenosis, atherosclerotic disease, aneurysms, and vascular malformations; its widespread application in neurovascular system requires evidence of good test-retest multi-site reproducibility. This study would like to assess the multi-center reproducibility, test-retest variability and inter-observer dependence of 4D flow MRI in neurovascular system.
