We could observe hemodynamic changes of the abdominal aorta under progressive lower limb exercise modes with rapid 3D cine PC on wide bore clinical 3.0T MR scanner. Not excessive, but mild exercise mode is optimum for maintaining vascular integrities by increasing the WSS and decreasing the OSI of the abdominal aorta.
