Cardiac Chamber quantification using magnetic resonance imaging at 7 Tesla--a pilot study
2 rating(s) (5 ø)

Short axis diastolic views free of cardiac motion effects. Short axis diastolic views obtained from breath-held base-to-apex 2D CINE FLASH acquisitions using (top) vector ECG, (middle) ACT and POX (bottom) gating. In this case of correct R-wave detection (subject 1), ECG-gated 2D CINE FLASH imaging was found to be immune to cardiac motion effects, as were ACT and POX gated acquisitions.
Conclusions: The applicability of acoustic triggering for cardiac CINE imaging at 7.0 T was demonstrated. ACT's trigger reliability and fidelity are superior to that of ECG and POX. ACT promises to be beneficial for cardiovascular magnetic resonance at ultra-high field strengths including 7.0 T.
