| Choice A: | overall image quality |
| Choice B: | modification of examination protocols |
| Choice C: | the need for in-service education |
| Choice D: | all of the above |
| Question 2: Transitioning from computed radiography to direct digital radiography is likely to ___________ reject rates. |
| Reference: | Little et al., "Unified database for rejected image analysis across multiple vendors in radiography," J Am Coll Radiol 14:208-216 (2017). |
| Choice A: | increase |
| Choice B: | decrease |
| Choice C: | not have an effect on |
| Question 3: The purpose of the IHE Scheduled Workflow integration profile is to: |
| Reference: | "ACR-AAPM-SIIM technical standard for electronic practice of medical imaging," Resolution 41 (2017).
Moore S, "Using the IHE scheduled workflow integration profile to drive modality efficiency," RadioGraphics 23:523-529 (2003). |
| Choice A: | Define the format of medical images and the transfer of images between devices |
| Choice B: | Describe a communication workflow for ordering/scheduling procedures, acquiring images, and transferring images to PACs that ensures continuity and integrity of imaging data |
| Choice C: | Define a standard for the electronic exchange of alphanumeric medical medical information |
| Choice D: | Establish a framework for storing patient medical histories in a permanent record |
| Question 4: Which tool best facilitates reject analysis by physicists, managers, lead technologists, and radiologists? |
| Reference: | Little et al., "Unified database for rejected image analysis across multiple vendors in radiography," J Am Coll Radiol 14:208-216 (2017). |
| Choice A: | An interactive dashboard/scorecard. |
| Choice B: | A shared Excel file with the exported acquisitions and rejects. |
| Choice C: | An SQL search interface. |
| Choice D: | A reject report on the modality system. |
| Question 5: According to Rosenkrantz et al, at least 50% of all repeat musculoskeletal and chest radiographs (additional acquisitions) were useful in providing additional information to address the clinical indication of the examination. |
| Reference: | Rosenkrantz AB, Jacobs JE, Jain N, et al. Technologist-directed repeat musculoskeletal and chest radiographs: How often do they impact diagnosis? AJR. 2017;209(6):1297-1301. |
| Choice A: | True |
| Choice B: | False |
| Question 6: Select the statement about Exposure Indices which is most accurate: |
| Reference: | A. Jamil, M.I. Mohd, N.M. Zain, THE CONSISTENCY OF EXPOSURE INDICATOR VALUES IN DIGITAL RADIOGRAPHY SYSTEMS, Radiation Protection Dosimetry (2018), Vol. 182, No. 4, pp. 413-418; S. Lewis, T. Pieterse, H. Lawrence. Retrospective evaluation of exposure in digital radiography, J Med Radiat Sci 66 (2019) 38–43. |
| Choice A: | Exposure indices provide clear and robust feedback to technologists about the appropriateness of an exposure. |
| Choice B: | For many body parts, appropriately acquired images may show high variability in their exposure index. |
| Choice C: | Images should be repeated if they show an exposure index of less than 1/2 the target EI. |
| Choice D: | Images should be repeated if they show an exposure index of less than 1/2 or greater than twice the target EI. |
