Summary
This study measured patient radiation doses during enteroclysis (small bowel enema) procedures. Doses were found to be intermediate compared to other barium examinations, providing valuable data for radiological safety.
Area of Science:
- Radiology and Medical Imaging
- Radiation Dosimetry
- Gastrointestinal Diagnostics
Background:
- Enteroclysis (small bowel enema) is an important diagnostic procedure.
- Understanding patient radiation dose is crucial for radiological safety.
- Comparative dose data for enteroclysis are needed.
Purpose of the Study:
- To quantify patient radiation doses for enteroclysis examinations.
- To compare these doses with other barium-based gastrointestinal studies.
- To evaluate the radiological procedure at John Radcliffe Hospital.
Main Methods:
- Acquired patient dose data for 23 adult enteroclysis examinations.
- Measured dose-area products and fluoroscopy times.
- Recorded the number of radiographs taken for dose assessment.
Main Results:
- The mean dose-area product was 6.8 Gy cm2.
- The mean effective dose was estimated at 1.5 mSv.
- Enteroclysis doses were intermediate between barium meals and barium enemas.
Conclusions:
- Patient radiation doses from enteroclysis are comparable to other barium studies.
- The findings provide essential data for optimizing radiological procedures.
- This research contributes to patient safety in gastrointestinal imaging.
