Keywords: Data Acquisition, BrainA new class of sequences, named T1 relaxation-enhanced steady-state (T1RESS), has been recently proposed and showed improved lesion conspicuity in contrast-enhanced exams. T1RESS sequences combine steady-state acquisition, either balanced or unbalanced with weak gradient spoiling, with periodic contrast-modifying preparation pulses to create T1 weighting of the contrast. Here, we present radial versions of T1RESS sequences using the stack-of-stars trajectory, which offer improved motion robustness and enable dynamic imaging through use of advanced reconstructions such as GRASP. Volunteer scans acquired at 3T are shown for both sequences. Moreover, the balanced version is demonstrated at 0.55T to highlight its SNR efficiency.
