Real-time cardiovascular magnetic resonance at 1.5 T using balanced SSFP and 40 ms resolution

Table 3 Evaluations of real-time and cine SSFP CMR (19 patients)

	Real-time CMR free breathing	Beat-to-beat variation	Cine CMR breath-holding
Myocardial mass/g	35.5 ± 10.5	± 4%	35.1 ± 10.5
Enddiastolic left-ventricular volume/ml	49.5 ± 13.9	± 3%	52.1 ± 18.2
Endsystolic left-ventricular volume/ml	26.7 ± 13.9	± 4%	24.4 ± 11.9
Stroke volume/ml	22.8 ± 5.2	± 7%	28.5 ± 15.7
Ejection fraction/%	49 ± 12^#	± 5%	55 ± 14

Values (mean ± standard deviation) were obtained from three short-axis views and averaged across patients (cine CMR covering 10–12 heartbeats) and cardiac cycles (real-time CMR, 5 consecutive heartbeats, beat-to-beat variation).
^#Statistically significant different from cine CMR (paired t test).
