Three Basic Principles to Guide Patient-Centered Imaging and Exposure to Ionizing Radiation

1. Justification principle: benefits and risks of all testing options should be compared, and if an exposure cannot be justified, the test should not be performed
2. Optimization principle: all doses due to medical exposure must be kept as low as reasonably achievable
3. Responsibility principle: both the referrer and the imager are responsible for justification of the test involving exposure to ionizing radiation
