Abstract: The phase shift component of MRI image was simulated for the tumors including the ferromagnetic particles by DDS which yielded the magnetic field distortion around the tumors. The simulation clearly visualized the shape and position of tumors. This method can image selectively only the tumors including the ferromagnetic particles by DDS, and so will be useful for the early finding of small tumor that are difflcult to be found by coventional techniques.

Keywords: MRI, tumor detection, ferromagnetic particles, visualization
