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.
