To assess measurement reproducibility and image quality of myocardial T and T maps using free-breathing slice-interleaved T and T mapping sequences at 1.5 Tesla (T). Eleven healthy subjects (33 ± 16 years; 6 males) underwent a slice-interleaved T and T mapping test/retest cardiac MR study at 1.5T on...
