Answer 5

1. Patient Identification
2. Area of Interest included
3. Anatomical Markers and Legends
4. Correct projection for a mobile chest X-ray
5. Correct exposure indicator
6. Optimum definition
7. Collimation to the area of interest
8. Are there any artefacts and are they obscuring the image?

Answer 6

IMAACREAP
I: identification, ensuring correct patient was imaged
M: markers are present and correct
A: anatomy of interest is assessed and adequately covered
A: artifacts are noted/assessed for
C: collimation present
R: relative position to the central beam (centering)
E: exposure is within range
A: any additional imaging required? (repeat, supplementary views)
P: pathology present that requires specialized projections i.e. horizontal beam hip?
