Contrast Volume and Type

N/A

Area Scanned

From just above acromioclavicular joint through scapular tip

Scan Delay

None

Length of Spiral (time)

40sec

Slice Thickness

3mm

Table Speed/Pitch

3-5mm/sec

Reconstruction Interval

2mm

3D Technique Used

Volume rendering and multiplanar obliques

Comment: The technique can be modified if only the humeral head is injured. In cases with complex trauma IV contrast may be used to exclude a vascular injury to the mediastinum. The protocol used would use 120ml of contrast injected at 2-3ml/sec with a 30sec delay.
