| Choice A: | When a patient undergoes multiple radiological examinations, accounting for all the examinations without consideration of dose is exposure tracking. |
| Choice B: | Tracking automatically implies assessing cumulative radiation dose to an individual. |
| Choice C: | Smart card project implied a card with the record of patient’s radiation exposures and dose |
| Choice D: | None of the above. |
| Question 2: Experience of patient exposure tracking indicates that it leads to ... |

| Choice A: | Strengthening the process of justification by avoiding another examination. |
| Choice B: | Strengthening the process of optimization. |
| Choice C: | Information for audit of patient doses for quality assurance purpose. |
| Choice D: | All of the above. |
| Question 3: Which best explains the sequence of steps for establishing radiation dose utilization in CT? |

| Choice A: | Body region based dose adjustment- indication based dose adjustment- appropriateness. |
| Choice B: | Appropriateness - indication based dose adjustment - patient size based dose adjustment. |
| Choice C: | Indication based dose adjustment - patient size based dose adjustment – triage. |
| Choice D: | Triage-age based dose adjustment-patient size based dose adjustment. |
| Question 4: Management of radiation dose involves the following except: |
| Reference: | Kalra MK, Sodickson AD, Mayo-Smith WW. CT Radiation: Key Concepts for Gentle and Wise Use. Radiographics. 2015 Oct;35(6):1706-21. |
| Choice A: | Continuous actions focused on dose reduction while maintaining image quality. |
| Choice B: | Tailoring radiation dose to clinical indication. |
| Choice C: | Adapting doses to patient body habitus. |
| Choice D: | Making sure no patient receives radiation dose above the recommended DRL. |
| Question 5: A Patient Exposure Tracking system can be used by a site to assess: |

| Choice A: | The effects of patient size on dose metrics for a specific protocol |
| Choice B: | The effects of patient size on diagnostic image quality |
| Choice C: | The relationship between dose metric values and image quality |
| Choice D: | The effects of radiation dose reduction technologies on image quality |
| Question 6: The American College of Radiology’s Dose Index Registry allows participants to: |

| Choice A: | Track cumulative dose metrics for individual patients across time. |
| Choice B: | Track cumulative dose metrics for individual patients even when their exams take place across different healthcare systems. |
| Choice C: | Compare an institution’s dose index values (e.g. CTDI, DLP) to national and regional averages for common imaging exams. |
| Choice D: | Determine threshold values to use in setting cumulative radiation dose alerts. |
