Improved Computed Tomography Contrast Injection Rates Through Implantable Chest Power Ports.

Abstract:

OBJECTIVE:The aim of this study was to optimize chest port contrast injections using stepwise improvements. METHODS:Ex vivo injections were tested. Two hundred scans using power port injections were then evaluated. RESULTS:The highest flow rate was achieved using a 19G access needle, larger diameter tubing, and warmed contrast.The mean injection rates in baseline and postimprovement groups were 2.7 ± 0.4 and 4.8 ± 0.4 mL/s, respectively (P < .0001). CONCLUSION:Component optimization of the port apparatus can maximize contrast flow rates.
