High-resolution cine MRI with TGRAPPA for fast assessment of left ventricular function at 3Â Tesla

Volumetric results of the TGRAPPA approach did not show significant differences to the STD approach for left ventricular ejection fraction (62.3 ± 10.6 vs. 61.0 ± 8.4, P = 0.2), end-diastolic volume (135.8 ± 47.5 vs. 130.8 ± 46.4, P = 0.07), endsystolic volume (53.0 ± 29.7 vs. 53.1 ± 32.7, P = 0.99) and myocardial mass (114.2 ± 32.5 vs. 114.6 ± 30.6, P = 0.9). Moreover, a comparison of peak ejection rate (601.3 ± 190.2 vs. 590.8 ± 218.2, P = 0.8) and peak filling rate (535.1 ± 191.2 vs. 535.4 ± 210.7, P = 0.99) did not reveal significant differences between the two groups. Limits in interobserver agreement were low for all systolic and diastolic parameters in both groups (P ≥ 0.05). Total acquisition time for STD was 273 ± 124 s and 34 ± 5 s for TGRAPPA (P ≤ 0.001). Evaluation time for standard and multislice approach was equal (10.8 ± 1.4 vs. 9.8 ± 2.1 min; P = 0.08).
