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.
