Purpose To develop a B1‐corrrected single flip‐angle continuous acquisition strategy with free‐breathing and cardiac self‐gating for spiral T1 mapping, and compare it to a previous dual flip‐angle technique. Methods Data were continuously acquired using a spiral‐out trajectory, rotated by the golden...
