1. A method of magnetic resonance imaging of moving substances, the method comprising;

  • (a) applying a first broadband 180 degree inversion pulse;

    (b) applying a 90 degree resonance excitation pulse and a first slice selection gradient;

    (c) applying a first read gradient;

    (d) applying a second broadband 180 degree inversion pulse;

    (e) applying second, complementary read and slice selection gradients which substantially zero the effective first moment in time;

    (f) applying phase encoding gradients;

    (g) receiving a magnetic resonance signal; and

    ,(h) reconstructing an image from the resonance signal.
