This presentation will demonstrate the methods for auditing computed tomography (CT) radiation dose for a patient population through the development of institutional dose reference levels that can be used for quality control. We will demonstrate how to use these dose reference levels in prospective monitoring of radiation by protocol, equipment and operator.
1. How can we demonstrate “As Low As Reasonably Achievable” in our institutions? Why is this important?
2. How have Dose Reference Levels (DRLs) been used in quality control and quality improvement for computed tomography?
3. What is the evidence that DRLs can affect optimum dose levels for CT?
4. How are LDRLs generated using an historical database of patient examination data?How is image quality taken into consideration in establishing LDRLs by protocol?
5. What are the best methods for sorting CT examination data by protocol/equipment for making DRL comparisons?
6. How is statistical significance determined for new LDRLs and how are new LDRLs used for prospective monitoring of radiation dose?
7. Adapting LDRLs for specific patient demographics: pediatrics, young adults, women
8. How can the CT radiation dose distributions by protocol be used to begin dose optimization?
