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.
