Abstract
A radioactive seed and method for making a radioactive seed with selective magnetic imaging characteristics are provided. The seed includes a housing which may include a metal shell for at least partially enclosing a radioactive material. The shell encloses a rod having a nickel layer with a phosphorous content, wherein the phosphorous content includes a level of phosphorous sufficient, when the seed is implanted in tissue, to provide a magnetic resonance image of the seed while substantially eliminating gross artifacts in the magnetic resonance image.
