Summary
This study quantified ovarian radiation dose during uterine artery embolisation (UAE). While doses were generally acceptable, findings suggest procedural optimization is possible to further reduce patient exposure.
Area of Science:
- Medical Imaging
- Radiation Oncology
- Interventional Radiology
Background:
- Uterine artery embolisation (UAE) is a common procedure.
- Ovarian radiation dose is a concern in UAE.
- Optimisation of radiation dose is crucial for patient safety.
Purpose of the Study:
- To quantify ovarian dose in patients undergoing UAE.
- To assess the optimisation level of ovarian radiation dose.
- To compare radiation doses across different angiography units.
Main Methods:
- Collected anatomical data and exposure parameters from 52 UAE patients.
- Utilised Monte Carlo simulation to calculate individual ovarian doses.
- Analysed performance of two angiography units based on collected data.
Main Results:
- Mean dose-area product was 196 Gy cm(2).
- Mean ovarian dose was 149 mGy.
- Performance analysis identified areas for potential improvement in radiation dose management.
Conclusions:
- Mean dose-area product and ovarian dose in UAE are currently acceptable.
- Opportunities exist to optimise UAE procedures for reduced radiation exposure.
- Improving angiography unit performance can enhance dose optimisation.
