Overview

Retrospective analysis assesses radiation dose values in pediatric contrast-enhanced CT, indicating a need for protocol optimization.

Key Points

  • This study aims to establish diagnostic reference levels for radiation doses in pediatric contrast-enhanced CT scans.
  • Conducted a retrospective analysis on data from 330 pediatric patients.
  • Collected information on CT scan parameters, total CTDIvol, and DLP.
  • Categorized patients into four age groups and compared findings with established DRL values.
  • Effective dose values for various scans ranged from 7.27 to 54.48 mSv.
  • No significant differences in CTDIvol and DLP for head and chest scans across age groups (P>0.05).
  • Significant differences in CTDIvol and DLP for liver, kidney, and abdominal scans were found among age groups (P<0.05).
