[Three-phase gadolinium infusion in moving-table three-dimensional MR angiography].
Moving-table three-dimensional (3D) MR angiography provides images of long segments of arteries. However, deep veins are sometimes superimposed on the arteries below the knee, and peripheral arteries sometimes fail to be visualized. We have developed an imaging method with three-phase gadolinium infusion according to the mean blood flow velocity of the leg. Nineteen patients with various blood flow velocities were studied. Eighteen of the patients had no venous superimposition. All 19 patients showed good configuration of peripheral arteries with 16-18 ml of gadolinium. This method is useful for better visualization of peripheral arteries without venous superimposition.
