Scanner UsedSiemens Somatom Plus 4
Injection RateN/A
Contrast Volume and TypeN/A
Area ScannedFrom just above acromioclavicular joint through scapular tip
Scan Delay None
Length of Spiral (time)40sec
Slice Thickness3mm
Table Speed/Pitch3-5mm/sec
Reconstruction Interval2mm
3D Technique UsedVolume 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.
