1. An improved diagnostic electrode for intracranial implantation to determine the foci of diseased brain tissue and including:

  • an electrode body;

    at least one metallic contact supported by the body;

    an electrical lead wire attached to the contact for connection to a diagnostic instrument;

    such metallic contact being made of an alloy which includes nickel and chromium and which is substantially devoid of iron;

    the electrode thereby providing an essentially artifactfree image of the location of such metallic contact when contact location is determined using magnetic resonance imaging techniques.
