HD catheters can be used to safely administer iodinated contrast media via mechanical power injection in in vitro operating conditions. Maximum peak pressure is below the manufacturer's 30 psi limit at flow rates up to 20 mL/s in double-lumen injections and up to 10 mL/s in single-lumen injections, which is higher than the usual maximum of 8 mL/s for CT angiography in clinical settings.
