Acetabulum/Pelvis: Evaluate suspected fracture

Specific Anatomic Region Acetabulum/Pelvis

Application Evaluate suspected fracture

Author Fishman EK

Reference Source Personal Communication

Scanner Used Siemens Plus4 Volume Zoom

KV / mAs / Time per Rotation (sec) 140 / 270 / 1 or 120 / 200 / .5

Detector Collimation (mm) 1

Slice Thickness (mm) 1.25

Data Reconstruction Interval (mm) 1 or 2

Table Speed (mm per rotation) / Pitch 5 / 5 or 6 / 6

Oral Contrast N/A

IV Contrast Volume and Type (if indicated) 120 cc of Omnipaque 350

Injection Rate 2 or 3 cc / sec

Scan Delay (sec) 30 or 60 sec

3D Technique Used Volume rendering

Comment: -In many cases of isolated pelvic injury, a noncontrast study is satisfactory. If, however, the possibility of vascular or bladder injury is suspected, then the protocol should be done with IV contrast, and a CT angiogram can also be done.
