Non Contrast
- Plan the Scan FOV (SFOV) box at topogram image
- Set the top line at the level above the shoulder
- Set the bottom line at the level of below the scapula angle.
- Ensure the lateral line to cover humerus soft tissue outline and thoracic spine / sternoclavicular join of the opposite side.
- Remind the patient to keep in place and not moving the affected arm / shoulder.
