Dynamic contrast-enhanced (DCE) MRI is being increasingly used in the detection and diagnosis of breast cancer. Cartesian sampling is routinely used however ghosting artifacts caused by cardiac motion are a well known challenge that in some instances can severely obscure the gland tissue, axilla and even known cancer. Radial sampling has an intrinsic advantage for diminishing motion artifacts by averaging low special frequency signals through oversampling of central k-space data. In this study, we demonstrated the feasibility of using a 3D stack-of-stars radial acquisition to provide motion free images of the entire breast region including the axilla.
