Determining exercise-induced blood flow reserve in lower extremities using phase contrast MRI.

PURPOSE To study the changes in limb blood flow during lower extremity exercise using phase contrast (PC) MRI in normal volunteers. MATERIALS AND METHODS Healthy volunteers performed plantar flexion exercise (<1 W) for four minutes. Flow velocity was measured using cardiac-gated, cine PC-MRI sequences (fast gradient recalled echo [GRE]; multishot echo… CONTINUE READING
