1. A magnetic resonance system obtaining an MR (magnetic resonance) angiography image of an imaging slice of a subject, comprising:

  • first means for performing a pre-sequence including a plurality of saturation pulses applied sequentially in time to the same pre-saturated slice of the subject which is positionally different from the imaging slice, said plurality of saturation pulses providing an MT effect, second means for thereafter performing a data acquisition sequence for acquiring MR signals from the imaging slice after the performance of the pre-sequence; and

    means for repeatedly operating said first and second means in succession and for producing an angiography image based on acquired MR signals.
