Intrabody MRI-compatible medical devices with a rigid stylet body with opposing distal and proximal ends with a wall enclosing at least one cavity extending therebetween. The stylet body has first and second laterally spaced apart and opposing external longitudinally extending recessed surfaces and at least one pair of transversely spaced apart apertures extending through the wall and at least one conductor having a length that extends through the cavity then exits the cavity to define at least one external loop extending between the distal end of the stylet body and the pair of transversely spaced apart apertures. First and second legs of each loop snugly abut a respective first and second recessed surface of the stylet body to thereby cooperate with the stylet body to define a substantially cylindrical shape. The at least one conductor with the at least one loop is configured to act as an MRI antenna.
