MRI examinations commonly involve a series of multiple imaging contrasts and MR-metrics. Dual or even more contrast techniques offer substantial scan time reduction and eliminate the propensity to slice co-registration errors induced by bulk and physiological motion. Recognizing this opportunity this work presents a dual contrast RARE-EPI hybrid, that provides T2 (RARE module) and T2* (EPI module) contrast and facilitates simultaneous T2 and T2* mapping in a single radially (under)sampled scan (2-in-1 RARE-EPI). The applicability of 2-in-1 RARE-EPI is demonstrated in phantom and in in vivo studies and benchmarked versus conventional T2 and T2* weighted/mapping techniques.
