This abstract presents a new approach to accelerated T1 mapping of the heart under free-breathing and without ECG. Compared with traditional radial sampling trajectory, spiral sampling offers the possibility to get ride of navigator data in the framework of “multitasking”, though at an extra cost of increased susceptibility to system imperfections such as gradient delay.
