Estimating fetal radiation dose from CT scans is crucial. This study measured doses in a phantom across various CT scanners and settings, providing data for improved accuracy.

Area of Science:

  • Medical Physics
  • Radiological Sciences
  • Diagnostic Imaging

Background:

  • Accurate estimation of fetal radiation dose from computed tomography (CT) scans is essential for patient safety.
  • Existing methods for dose estimation can be complex and require refinement for clinical application.

Purpose of the Study:

  • To simplify and enhance the accuracy of fetal radiation dose estimation from CT procedures.
  • To provide empirical data on fetal dose measurements across different CT scanner models and operational parameters.

Main Methods:

  • Fetal doses were measured using an adult anthropomorphic phantom across four CT scanner models (Picker 1200, Siemens DRH, GE 9800, GE 8800).
  • Measurements were conducted varying kilovoltage (100-140 kVp), slice thickness (2-10 mm), scan angles (360°, 398°), and patient orientation (prone, supine).

  • CT Dose Index (CTDI) was measured using a pencil ionization chamber within a 16-cm-diameter cylindrical phantom.

    • Main Results:

    • Empirical fetal dose data were collected for multiple CT scanners under diverse scanning conditions.
    • Measurements demonstrated reasonable agreement with previously published data, considering variations in phantom types, X-ray tube output, and equipment calibration.

    Conclusions:

    • The study provides valuable reference data for estimating fetal radiation doses from CT examinations.
    • The findings support the development of more accurate and standardized protocols for dose assessment in pregnant patients undergoing CT scans.
