    High-flow contrast administration via high-pressure central venous catheters (HP CVC) was evaluated for enhancing CECT image quality in critically ill patients.

  • 2

    The study involved 75 patients, comparing CECT images obtained with standard CVC and HP CVC, focusing on flow rates and image quality metrics.

  • 3

    HP CVC allowed a significantly higher median flow rate of 7.7 mL/s compared to 3.5 mL/s for standard CVC, but did not improve image quality.

  • 4

    Objective image quality was assessed using signal-to-noise ratio (SNR) and contrast-to-noise ratio (CNR) without significant differences between groups.

  • 5

    The use of HP CVC for high-flow CM injection was safe, but further studies are needed to explore its effects in specific patient populations.
