Aim of this study is to investigate the feasibility of phase contrast imaging for assessment of muscle function in children with cerebral palsy (CP). Time-resolved cine phase contrast MRI was synchronized with electrical muscle stimulation of the calf muscle at a clinical 3T MRI scanner. 11 healthy and 4 children with hemiparetic CP were scanned. Dynamic velocity, strain, and strain rate maps were reconstructed. Synchronous dynamic PC MRI of electrically stimulated muscle is feasible in children, even in CP patients and might provide further insight into the health status of their muscles.
