Free breathing cine bSSFP sequences with minimal compromises in spatio-temporal resolution requirements are highly desirable in patients who can not hold their breath, e.g., sedated patients, patients with poor cardiopulmonary reserve, patients with arrhythmia etc. The results from this prospective clinical study of 14 clinical patients shows that a cardiorespiratory synchronized (CS) sequence can reduce specific energy deposition (0.68 ± 0.24 kJ/kg) by 40% compared to a respiratory gated (RG) sequence (1.2 ± 0.36 kJ/kg) without compromising spatial, temporal, and contrast resolution thus permitting the prescription of bSSFP cine sequences with higher spatial or temporal resolution, and coverage.
