Author Information
Author(s): Muacevic Alexander, Adler John R, Mahmoud Adil M
Primary Institution: Azadi Teaching Hospital, Duhok, IRQ
Hypothesis
This study aims to document and compare the radiation doses from chest CT scans performed at two imaging centers in Duhok Province.
Conclusion
The study highlights disparities in radiation doses for chest CT scans between two medical institutions, suggesting a need for dose optimization strategies.
Supporting Evidence
- The mean CTDIvol was 279.39 mGy at Azadi Teaching Hospital and 227.14 mGy at the 3-Tesla Center.
- The mean DLP values were 655.14 mGy·cm at Azadi Teaching Hospital and 789.61 mGy·cm at the 3-Tesla Center.
- The mean effective dose was 9.171 mSv at Azadi Teaching Hospital and 11.054 mSv at the 3-Tesla Center.
- Statistically significant differences were observed in mAs, DLP, and ED values between the two sites.
Takeaway
The study looked at how much radiation patients get from chest CT scans at two hospitals and found differences that could be improved.
Methodology
Data were collected from daily records of unenhanced chest CT scans for 200 patients, with analysis performed using IBM SPSS Statistics.
Potential Biases
Potential biases may arise from differences in equipment calibration and staff training between the two facilities.
Limitations
The study did not standardize patient height or body size, which may affect scan length and radiation exposure.
Participant Demographics
The study included 200 patients, with a nearly equal gender distribution and most patients aged between 61 and 70.
