Purpose To develop a framework for prospective free‐induction decay (FID)‐based navigator gating for suppression of motion artifacts in carotid magnetic resonance imaging (MRI) and to assess its capability in vivo. Materials and Methods An FID‐navigator, comprising a spatially selective low flip‐ang...
