2D TOF MRA provides important diagnostic information around carotid bifurcation. However, the image is prone to artifacts caused by pulsatile flow. The present work utilized Temporal Harmonic Encoding scheme to reduce these artifacts by extracting only the static signals for MRA. Meanwhile, the harmonic components containing dynamic information could also be used as a reference.
