  9. Patterns are Your Clue PCP Pneumonia CHF Interstitial Lung Disease - Acute

  10. Patterns are Your Clue Pneumonia Alveolar edema Air Space Consolidation

  11. Patterns are Your Clue

  12. Patterns are Your Clue SB > 3cm Continuous valvulae Paucity colonic gas Multiple non-colonic A/F levels

  13. Basic Concepts • One view is no view – use it all! • Patterns are your clue • Be sure you are looking • Know what you’re looking for • Know the limits of your test

  14. Be Sure You are Looking RT Kartegener’s Syndrome

  18. Know What You’re Looking For PNEUMOTHORAX Skin fold – no intervention Gray edge with peripheral markings Failed line placement, SOB: Thin line without peripheral lung markings = pneumothorax

  19. Know What You’re Looking For Pneumothorax + mediastinal shift = Tension Pneumothorax

  25. Know What You’re Looking For PNEUMOPERITONEUM Supine – Double Bowel Wall Sign Outlining of liver/GB

  26. Know What You’re Looking For 35 year old with recurrent abdominal pain: Extensive pancreatic calcification = recurrent pancreatitis
