Axial Coronal
Incidental Mandibular Fracture
Zygomatic Arch Fx.
Chest
Fractured Ribs– 1-3 indicate High Impact - look for other injury
PTX & Hemothorax Aneurysm Rib FX may cause other abdominal injury
Fractured Sternum
Pneumothorax
Dissecting Aneurysm

Fractured Rib
Fractured Ribs sharp and pointy...
Abdomen Scan vs. DPL
CT Scan + Less Invasive + Solid Organ
Lacerations + Retroperitoneal Bleed - Contrast Injection - Not sensitive to bowel
injury Decreasing Hct.(6 points)
DPL + Can be preformed
anywhere + Bowel Lacerations - Retroperitoneal Bleed - More Invasive
Liver Laceration
Kidney Laceration
Sometimes we see spinal fractures on abdominal scans.
