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. Copyright © 2020 Wolters Kluwer Health, Inc. All rights reserved.
