ABSTRACT:
Systems and techniques for acquiring a medical image of a region of interest are described. A plurality of electromagnetic excitation pulses are applied to the region of interest according to predetermined parameters, and a predetermined delay period is introduced after which the longitudinal magnetization of a first species generated within the region of interest reaches zero and a longitudinal magnetization of a second species generated within the region of interest is in steady-state.
