In this work, we investigated the feasibility of black-blood imaging of peripheral arteries using a spin-echo spiral sequence with flow-spoiling gradients. Instead of the upstream spin inversion or saturation, the black blood is caused by the dephasing effect from the moments of the flow-spoiling gradients in the imaging region. The results show that black-blood imaging of peripheral arteries using a spin-echo spiral sequence with flow-spoiling gradients is feasible. Using gradients with a large first moment dephase the flow signal at the cost of a longer echo time.
