Summary
This study found higher patient radiation doses during enteroclysis examinations than previously reported. Findings suggest a need to review examination techniques to reduce radiation exposure while maintaining diagnostic quality.
Area of Science:
- Radiology
- Medical Physics
- Radiation Protection
Background:
- Enteroclysis is an imaging procedure requiring significant radiation exposure.
- Optimizing radiation dose in diagnostic imaging is crucial for patient safety.
Purpose of the Study:
- To quantify patient radiation doses during enteroclysis procedures.
- To compare these doses with existing literature values.
- To identify potential areas for dose reduction.
Main Methods:
- Dose-area product (DAP), fluoroscopy time, and radiograph counts were recorded for 14 enteroclysis examinations.
- Entrance surface dose (ESD) and effective dose (E) were estimated from collected data.
- Radiation dose contributions from fluoroscopy and radiography were analyzed.
Main Results:
- Mean DAP was 81 Gy cm², with a mean fluoroscopy time of 19.5 minutes.
- Fluoroscopy accounted for 77% of the DAP.
- Mean ESD was 428 mGy and mean effective dose (E) was 21 mSv.
Conclusions:
- Patient doses, including DAP and fluoroscopy time, were higher than reported in previous studies.
- Current enteroclysis examination techniques may require revision.
- Strategies to reduce patient radiation exposure without compromising diagnostic quality should be implemented.
