The
chemical shift based IDEAL decomposition method generally requires redundant
sampling at multiple time points. A
unique undersampled radial k-space trajectory at each echo time provides a
means to accelerate data acquisition while still allowing for robust chemical
species decomposition. In this work we present a dual-pass dual-half-echo
radial acquisition which utilizes undersampled source images with IDEAL to
achieve bSSFP images with high isotropic resolution and robust fat-water
separation in the breast and knee.
