Results or findings
Results:
1. What is the approximate equivalent dose in “CXRs” for the following examinations ? (one CXR= 0.02 mSv)
2. What is the approximate lifetime additional risk of fatal cancer for performing the following radiological investigations?
Limitations/ points of discussion:
- Small study numbers.
- There are constantly evolving radiation reducing imaging technologies and techniques.
- Individual doses are heavily dependent on patient age, sex, weight etc.
- Retrospective studies looking at cancer risk require follow up over a long period of time. This means data on cancer risk is not up to date and significantly at risk of confounding.
- At low-dose radiation even large epidemiological studies would not have the statistical power to detect increased cancer risk. [6]
