We proposed a method to obtain MRA simultaneously with 3D quantitative MR parameter maps. The method calculates MRA by combining images and maps obtained using MR parameter mapping with weights that change in the head-to-neck direction in order to correct for the effect of blood flow. The method was evaluated with five healthy volunteers. It visualized the visibility of blood vessels and correlation of intensity with time-of-flight MRA more effectively than conventional calculation method. This suggests that the proposed method is effective for simultaneously obtaining computational MRA and MR parameter maps.
