1. A power-injectable access port, comprising:
- a housing defining an internal cavity, a bottom wall of the internal cavity, and an outwardly facing bottom surface, the bottom wall comprising a metal, the housing including a plurality of suture apertures;
a needle-penetrable septum captured by the housing enabling needle access to the internal cavity;
a stem having a lumen in fluid communication with the internal cavity, the stem configured for coupling to a catheter; and
a radiopaque identification feature observable via imaging technology, the radiopaque identification feature positioned on the outwardly facing bottom surface etched into the metal;
wherein subsequent to subcutaneous implantation of the power-injectable access port, the radiopaque identification feature conveys to an observer using the imaging technology that the power-injectable access port is suitable for power injection.
