Magnetization transfer time-of-flight magnetic resonance angiography.
Time-of-flight (TOF) angiography based on inflow enhancement is limited by the steady-state signal differences between blood and the surrounding stationary tissues. We present a new TOF sequence in which magnetization transfer contrast is used to supplement wash-in effects. Angiograms demonstrating the superior performance of this technique are presented.
