Abstract
A method of performing a power injection procedure, including 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. The access port defines one or more fluid reservoirs, each fluid reservoir accessible through a cannula-penetrable septum. The method further includes identifying the indicating radiographic feature on the x-ray, and in accordance with the presence of the indicating feature on the x-ray, flowing a fluid through the access port at a rate of at least about 1 milliliter per second.
