Color-coded CT protocols significantly reduce errors in pediatric imaging compared to conventional methods. Technologists also preferred the color-coded system for its ease of use and clarity.

Area of Science:

  • Radiology
  • Medical Imaging
  • Pediatric Imaging

Background:

  • Pediatric CT technique requires specific adjustments for infants and children.
  • The Broselow-Luten pediatric system, a size-based color-coded tool, simplifies pediatric care and reduces medical errors.
  • This color-coded system can be adapted for CT protocols.

Purpose of the Study:

  • To compare error occurrence between conventional and color-coded pediatric multidetector body CT protocols.
  • To assess technologist preference for conventional versus color-coded CT protocol formats.

Main Methods:

  • Multidetector CT examinations were conducted using conventional or color-coded formats for 6-week periods.
  • Variations from protocol parameters (tube current, detector configuration, table speed, IV contrast dose) were recorded.

  • CT technologists (n=20) completed a survey on format preference, ease of use, and clarity.

    • Main Results:

    • The color-coded group showed significantly fewer overall errors (p < 0.01).
    • Error percentages for radiation dose parameters (tube current, detector configuration, table speed) were significantly lower in the color-coded group (p < 0.05).
    • The color-coded format was overwhelmingly preferred by technologists (p < 0.0003).

    Conclusions:

    • Color-coded CT formatting, an extension of existing clinical systems, offers an efficient and consistent approach for pediatric body CT.
    • This system simplifies protocol use and reduces variations (errors) in radiology departments.
    • The color-coded system is a preferable format for general pediatric body CT protocols.
