Magnetic resonance imaging (MRI) near metallic implants remains an unmet need because of severe artifacts, which mainly stem from large metal-induced field inhomogeneities. The single-scan cross spatiotemporal encoding (xSPEN) technique delivers in-plane distortion-free 2D images under such large field inhomogeneity condition, while the slice-plane displacement, “signal voids” and “pile-up” effects are proposed to be solved by applying t₁-evolution-time encoding on the multi-slicing 2D xSPEN technique. Compared to the popular “SEMAC” and “MAVIC” techniques, the remarkable time efficiency of this t₁-encoding xSPEN thus enable many advanced MRI applications near metal implants with another additional dimension, such as diffusing MRI, function MRI.
