We present a fast alternative to Bloch simulation for simulation of off-resonance artifacts in steady-state imaging. By assuming a steady-state, the signal equation can be quickly evaluated by using multiple Fast Fourier Transforms. We show an acceleration factor of over 350 for a 2D simulation of a titanium cylinder phantom, while the differences with Bloch simulation were minor. The speed of the proposed method enables 3D simulations at high resolution and may benefit various applications.
