1. A magnetic resonance imaging (MRI) system comprising an MRI gantry and controlling computer system including at least one programmed computer configured to:

  • effect a cardiac-triggered time-SLIP (spatial labeling inversion pulse) MRI data acquisition sequence for imaging blood perfusion in imaged patient tissue and employing therewithin an MRI cine sub-sequence, which cine sub-sequence is positioned in the time domain to encompass at least part of a predetermined cardiac time interval of the patient;

    process acquired data from the time-SLIP data acquisition sequence to generate a sequence of MRI cine frame images having respectively associated different effective BBTI (black blood time to inversion) time intervals;

    identify one of said MRI cine frame images as acceptable, thereby effectively also determining an appropriate BBTI time interval for the patient; and

    output a time-SLIP image based on said determined appropriate BBTI time interval to at least one of (a) a display, (b) a remote system or (c) a non-transitory storage medium.
