Abstract
A method of power injecting a contrast medium into a patient, including obtaining a power-injectable access port suitable for power injection. The power injectable access port includes a housing defining a reservoir, and a septum. The septum may include a self-sealing material, and a radiopaque material. The radiopaque material may form a selected pattern when an x-ray is taken through the septum for identifying the power-injectable access port as being suitable for power injection. The power-injectable access port may be structured for accommodating a pressure developed within the reservoir of at least 35 psi, and may be designed to accommodate a fluid flow rate of at least 1 milliliter per second. After implanting the power-injectable access port in the patient, the method may include imaging the power-injectable access port and confirming via the selected pattern in the septum that the power-injectable access port is suitable for injecting the contrast medium.
