We explored the feasibility to accurately assess left ventricular (LV) dimensions and function at 7T by using 2D FGRE cine imaging and comparing the results to SSFP at 1.5T as the current gold standard. FGRE at 7.0T provided excellent blood/myocardium contrast and LV parameters with close agreement to SSFP. Thus, the combination of small slice thickness (4mm) and ultrahigh field together wit local TX/RX coils facilitated a sufficient SNR and CNR, which holds the promise for accurate functional cardiac imaging at 7T.
