J Comput Assist Tomogr. 2020 Nov/Dec;44(6):911-913. doi: 10.1097/RCT.0000000000001048.

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.
