A magnetic resonance imaging (MRI) system using an MRI gantry and controlling computer system includes 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. The sub-sequence is positioned in the time domain to encompass at least part of a predetermined (e.g., diastolic) cardiac time interval of the patient. Processing acquired data from the time-SLIP data acquisition sequence generates a sequence of MRI cine frame images having respectively associated different effective BBTI (black blood time to inversion) time intervals. Identifying one of the MRI cine frame images as acceptable, thereby effectively also determines an appropriate BBTI time interval for the patient. The system then outputs a time-SLIP image based on the determined appropriate BBTI time interval to at least one of (a) a display, (b) a remote system or (c) a non-transitory storage medium.
