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.
