Recently, a novel method has been developed for myocardial 3D quantification of both T1 and T2 with whole coverage of the left ventricular myocardium within one breath hold (3D-QALAS). In this work we validate 3D-QALAS in-vivo by comparison with MOLLI-sequence for myocardial T1-mapping and multi-echo for myocardial T2-mapping. Relaxation times measurements obtained with 3D-QALAS correspond well with data from existing 2D mapping methods and allows a fast acquisition that provides information about both T1 and T2, making the method clinically applicable to a broader spectrum of diseases.
