- Abdomen Evaluation
- 1. Identifaction
- Patients full name
- 4. Correct projection
- Long axis of spine coincident with mid line of image
- Spinous processes visible
- Symmetrical iliac fossae and obturator foramen
- Sacrum is central in pelvic inlet
- 2. Aspect markers
- In the primary beam or post-processing
- 6. Image denisty
- The amount of image blackening without compromising image contrast
- Bone is weight, fat is dark grey and air is black
- The amount of image blackening without compromising image contrast
- 8. Collimation
- Must include AOI
- Accuracy reduces radiation dose
- 9. Artefacts and pathology
- Removed trousers, buttons, zips etc.
- Kidney stones, swallowed FB?
- 10. Repeats
- Cross renal
- Bladder view
- Any external arefacts obsecuring pahtology?
- 7. Image sharpness
- Patient movement
- Should be minimised by the supine postion
- Geometric
- Patient movement
- 5. Image contrast
- The difference between densities of two adjacent areas
- Bony trabeculae seen
- Soft tissue structures visibile e.g. bladder
- The difference between densities of two adjacent areas
- 1. Identifaction
- 3. AOI
- Superior: as much as upper abdomen as possible
- Lateral: lateral borders of abdomen
- Inferior: lower border of symphysis pubis
