Tissue hypoxia plays a key role in the development and progression of cardiac and renal diseases. Blood oxygenation level dependent magnetic resonance imaging (BOLD-MRI) is the most promising imaging technique to monitor tissue oxygenation in humans. Cardiorenal syndrome is widely accepted as a complex clinical problem routinely faced by clinicians. However, the mechanism from the viewpoint of oxygenation is not understood. We analyses simultaneously myocardial and renal oxygenation using T2* cardiac MRI (T2*-CMR) and investigates the cardiorenal relationship.
