We proposed an inversion recovery respiratory and cardiac self-gated continuous spiral acquisition pulse sequence to acquire cine and LGE images simultaneously. Data is acquired using a single spiral interleaf, rotated by the golden-angle in time, with an inversion pulse applied every 5 seconds. Cine images were reconstructed from the steady state portion of the signal using L+S, while LGE images were reconstructed from the data at a specific TI after each inversion pulse using SPIRiT. This strategy will enable whole heart cine and LGE imaging in less than 5 minutes without the need for breath holding or ECG gating.
