| Research Abstract |
We proved MRI can visualize the area where blood diluted with saline. We confirmed that dilution of blood gained blood signal intensity change in static and flow phantom. FFE T2* weight lower thigh images ware obtained before and during injection of saline from dorsalis pedis vein. We subtract images before injection form images during injection. These subtraction images visualized the vein where saline was injected.
