Adequate perfusion is essential for muscle function and tissue health. Vascular complications are a common problem in several diseases like diabetes mellitus. Arterial spin labeling represents a non-invasive assessment of tissue perfusion using magnetically labeled blood water as an endogeneous tracer. ASL has been used to measure dynamic changes in skeletal muscle perfusion during and after exercise (plantar flexion). In this study we demonstrate the feasibility of measuring ASL in aerobic exercise at 7 Tesla with a high temporal resolution and good SNR and high intra-individual reproducibility.
