(a) The RINEPT-FSSFP RF pulse sequence contains a 2 s presaturation pulse (Presat), a refocused INEPT block (RINEPT), and FSSFP imaging block using a low power frequency selective Gaussian pulse for detection. τINEPT represents the INEPT delay, while τrefocus is the refocusing delay, (b) Double RINEPT-FSSFP RF pulse sequence with extra RINEPT block for prepolarization of 13C from more polarized protons of thermally polarized phantoms in sodium 1-13C-acetate.
