An implantable port for accessing internal body structures, the port comprises a proximal housing including an opening providing access to an interior of the port and a distal housing adapted for assembly with the proximal housing, the distal housing including a reservoir which, when the distal housing is mated with the proximal housing is in fluid communication with the opening of the proximal housing in combination with a radiopaque element in one of the proximal and distal housings, a shape of the radiopaque element identifying, when imaged, a structural characteristic of the port not otherwise identifiable visually.
