3D B1+ corrected simultaneous myocardial T1 and T1ρ mapping with subject‐specific respiratory motion correction and water‐fat separation

Purpose To develop a 3D free‐breathing cardiac multi‐parametric mapping framework that is robust to confounders of respiratory motion, fat, and B1+ inhomogeneities and validate it for joint myocardial T1 and T1ρ mapping at 3T. Methods An electrocardiogram‐triggered sequence with dual‐echo Dixon read...
