 Abstract: Imaging of hyperpolarized 13C has recently gained interest for metabolic imaging. In comparison with 1H imaging, the signal of hyperpolarized substances cannot build up a steady state during an imaging sequence as it decays irreversibly to its thermal equilibrium value. Therefore, TrueFISP (FIESTA, balanced SSFP, b-FFE) and single-shot RARE (TSE, FSE) show comparable signal behaviour for on-resonance signal. However, TrueFISP images of hyperpolarized substances suffer in general from off-resonance signal in contrast to RARE. We demonstrate that due to off-resonance effects, TrueFISP has no advantage in comparison with RARE when hyperpolarized substances are imaged.
