1. A method of generating an MRI image of a medical device and proximate body tissue in which the device is located, wherein the medical device has incorporated therein an imaging material comprising selected MRI detectable nuclei, the method comprising: performing a first MRI process on a body portion including at least a portion of the medical device to obtain first image data, wherein the first MRI process is adapted to detect MRI detectable nuclei present in the proximate body tissue; performing a second MRI process on the body portion to obtain second image data, wherein the second MRI process is adapted to detect the selected MRI detectable nuclei contained in the medical device imaging material and the selected MRI detectable nuclei is not the same nuclei that the first MRI process is adapted to detect; and combining the second image data with the first image data to produce combined image data for the medical device and the proximate body tissue, and that indicates the relative position of the medical device within the proximate body tissue.
