This study reports on early experiences made with cardiac black blood RARE imaging at 7.0 T in healthy volunteers and patients with hypertrophic cardiomyopathy. Our preliminary results underscore that cardiac black blood imaging at 7.0 T remains challenging in in patients. The main obstacles causing suboptimal image quality identified here were motion induced artifacts due to non-compliance with the breath-hold regime, mis-triggering due to cardiac arrhythmia and acquisition window timing within the cardiac cycle. It's concluded that further developments are essential to translate the benefits of high resolution black blood imaging at 7.0 T into a clinical setting.
