1. A method of performing a power injection procedure, comprising:
- taking an x-ray of a subcutaneously implanted access port in a patient to determine whether the access port includes a radiographic feature indicating that the access port is suitable for flowing fluid at a rate of at least 1 milliliter per second through the access port, the access port defining one or more fluid reservoirs, each fluid reservoir accessible through a cannula-penetrable septum;
identifying the indicating radiographic feature on the x-ray; and
flowing a fluid through the access port at a rate of at least 1 milliliter per second.

Abstract
Methods of performing a power injection procedure are described. One method includes taking an x-ray of a subcutaneously implanted access port in a patient to determine whether the access port includes a radiographic feature indicating that the access port is suitable for flowing fluid at a rate of at least about 1 milliliter per second through the access port, identifying the indicating radiographic feature on the x-ray, and flowing a fluid through the access port at a rate of at least about 1 milliliter per second.

8. A method of performing a power injection procedure, comprising:
-
providing an access port including a cannula-impenetrable housing and a radiographic feature indicating that the access port is suitable for flowing fluid at a rate of at least 1 milliliter per second through the access port; implanting the access port in a subcutaneous pocket formed under a patient'"'"'s skin; taking an image of the implanted access port via imaging technology; identifying the access port as being suitable for flowing fluid at a rate of at least 1 milliliter per second through the access port via the image of the radiographic feature of the access port; and injecting contrast media fluid through the access port at a rate of at least 1 milliliter per second. - View Dependent Claims (9, 10, 11, 12, 13)

14. A method of performing a power injection procedure, comprising:
-
implanting an access port including a fluid reservoir accessible through a septum and a radiographic feature, the radiographic feature indicating that the access port is capable of handling pressures associated with power injection; taking an image of the implanted access port via imaging technology; identifying the access port as capable of handling pressures associated with power injection via the image of the radiographic feature of the access port; palpating the access port to identify the location of the septum; inserting a needle through a septum, the needle connected to tubing and in fluid communication therewith, the needle and tubing structured to accommodate a fluid pressure of at least 400 psi; and injecting contrast media fluid through the tubing and needle to induce a pressure within the access port in the range of 37 psi and 65 psi.
