In stratification of heart valve diseases blood flow assessment often plays a key role. When echocardiography struggles, phase contrast magnetic resonance imaging (PC-MRI) may be considered as an alternative (Srichai et al. AJR 2009). Arrhythmias are a major limitation of conventional segmented PC-MRI (SEG). Real-time sequences (RT) could overcome it. The purpose of this study is to evaluate RT in a flow model as well as in volunteers and patients. We hypothesize to measure equal velocities and flow compared to SEG as reference in sinus rhythm and aimed to show feasibility in atrial fibrillation (Afib).
The evaluated real-time PC sequence can access flow reliably and in good correlation to a conventional segmented version in model experiments, volunteers and patients. Hence it might become an useful alternative to doppler echocardiography in arrhythmic patients.
