We have developed a k+ind of Magnetic Resonance Angiography(MRA) techniques,which is called the walking multi-slice and subtraction MRA. In this technique,using subtracted conventional flow refocused gradient Field Echo (FE) multi-slice images,the MRA image distinguished arteries and veins of the lower extremities is obtained. In this taper,we report an ew designed MRI scan condition and some additional image processing for this technique to improve the spatia1 resolution in the direction of the slicing.
