This study established optimal power injection protocols for pediatric hepatic CT scans using ioversol. Recommended injection rates and timing vary by scan technique to ensure effective contrast delivery and patient safety.

Area of Science:

  • Radiology
  • Pediatric Imaging
  • Medical Imaging Contrast Agents

Background:

  • Pediatric hepatic computed tomography (CT) requires precise contrast media administration.
  • Optimizing injection protocols is crucial for diagnostic image quality and patient safety.

Purpose of the Study:

  • To determine an effective power injection protocol for pediatric hepatic CT.
  • To evaluate the safety and efficacy of power injection in pediatric patients.

Main Methods:

  • Eighty-seven pediatric hepatic CT studies were prospectively analyzed.
  • Ioversol (320 mg iodine/cc) was administered at 2 cc/kg using power injection.
  • Three scanning techniques were employed: helical, dynamic non-breath-hold, and dynamic breath-hold.
  • Injection rates (cc/kg/min) and scan initiation times were systematically varied and analyzed.

Main Results:

  • Optimal scanning intervals were achieved with specific injection rates: 165s for 1.2-1.5 cc/kg/min, 120s for 1.51-2.0 cc/kg/min, and 90s for 2.01-2.4 cc/kg/min.
  • Hepatic attenuation did not significantly increase with injection rates above 2.01-2.4 cc/kg/min compared to 1.51-2.0 cc/kg/min.
  • Power injection was found to be safe, with only one minor complication related to central line injection.

Conclusions:

  • Specific power injection protocols were determined for different pediatric hepatic CT techniques.
  • Helical studies: 1.7-2.0 cc/kg/min initiated at 60s.
  • Dynamic non-breath-hold: 1.5-1.7 cc/kg/min initiated at 50s.
  • Dynamic breath-hold: 1.2-1.5 cc/kg/min initiated at 45s.
  • Power injection is a safe and effective method for contrast administration in pediatric hepatic CT.
