Test–retest multisite reproducibility of neurovascular 4D flow MRI

Background 4D flow MRI shows great potential in neurovascular disorders such as stenosis, atherosclerotic disease, aneurysms, and vascular malformations. Its widespread application in the neurovascular system requires evidence of good test–retest multicenter reproducibility. Purpose To assess the multicenter reproducibility, test–retest reliability and interobserver dependence of 4D flow MRI in measurements of cerebral blood flow/velocity in...
