This abstract presents a new approach to accelerated T1 mapping of the heart under free-breathing and without ECG. The proposed approach is still within the “multitasking” framework, but requires no navigator data.
Figure 2. Typical volunteer multitasking images. (a) 30.7s imaging data were acquired and used for spiral, navigator-less multitasking reconstruction. (b) Both imaging data and navigator data were acquired from a total of 61.4s scan and used for spiral multitasking reconstruction.
