Free-breathing, motion-corrected, highly efficient whole heart T2 mapping at 3T with hybrid radial-cartesian trajectory

Purpose To develop and test a time‐efficient, free‐breathing, whole heart T2 mapping technique at 3.0T. Methods ECG‐triggered three‐dimensional (3D) images were acquired with different T2 preparations at 3.0T during free breathing. Respiratory motion was corrected with a navigator‐guided motion corr...
