Abstract

Embodiments herein provide T1-mapping using a phase-sensitive inversion-recovery (IR) method. The method may use phase information of IR sequence data to restore the polarity of the IR sequence data. Restoring the polarity effectively doubles the dynamic range of the IR sequence data, providing for higher accuracy of T1-mapping. The technique may also allow a smaller number of inversion time (TI) intervals to be used for accurate T1-mapping, thereby reducing data acquisition time.
