Due to the off-resonant blurring of fat, image quality can be severely degraded with radial acquisition. This is particularly problematic for low receiver bandwidths (e.g. 280 Hz/px, first row, left hand-side). Although the effect is less evident for higher bandwidths (e.g. 780 Hz/px, second row), slight blurring is still visible when no correction is applied (arrow). By properly modeling this effect in the reconstructions, sharp fat images can be obtained (right-hand side).
