Focused navigation for respiratory–motion‐corrected free‐running radial <scp>4D</scp> flow <scp>MRI</scp>

Abstract

fNAV corrected respiratory motion in vitro and in vivo, resulting in fNAV 4D flow measurements that are comparable to those derived from 2D flow and navigator-gated Cartesian 4D flow datasets, with improvements over those from uncorrected 4D flow.
