A free-breathing late gadolinium enhancement scan may be beneficial for patients who have difficulty with breath-holds. However, the fast data acquisition needed may be difficult to achieve at low field strengths. Here, an undersampled spiral (R=3) acquisition with a through-time spiral GRAPPA reconstruction is used to achieve high spatial (1.25 x 1.25 mm2) and temporal (139 ms acquisition window) resolution for LGE imaging at 0.55T. The resulting images have qualitatively good contrast-to-noise between lesions and healthy myocardium, with acceptable SNR and without motion blurring.
