This document provides an overview of interpreting chest x-rays and identifies several key factors. It discusses the importance of inspiration, penetration, and rotation in obtaining a technically quality radiograph. It also outlines different views of chest x-rays including PA, AP, and lateral views. Finally, it identifies several anatomical structures that should be evaluated when interpreting a chest x-ray such as the lungs, heart, diaphragm, bones, and soft tissues.

1. BASIC
INTERPRETATION
OF CHEST X RAY

3. INTRODUCTION

5. GENERAL PRINCIPLES

6. RELATIVE DENSITIES

8. BEFORE INTEREPTING CHEST
RADIOGRAPH

9. VIEWS OF CHEST RADIOGRAPH

10. PA VIEW

14. AP VIEW

19. LATERAL VIEW

21. LATERAL DECUBITUS POSITION

23. ERECT
“BETTER” THAN SUPINE
PLEURAL FLUID
“MOVES” TO BASES
GASTRIC AIR -
FLUID LEVEL
PLEURAL AIR “RISES” TO APEX

24. ERECT
NORMAL PULMONARY BLOOD DISTRIBUTION

25. PLEURAL AIR GRAVITATES SUPERIORLY
PLEURAL FLUID GRAVITATES INFERIORLY
SUPINEMAY DISPERSE FLUID (EFFUSIONS) / HIDE AIR (PNEUMOTHORAX)

26. SUPINE
PULMONARY VESSELS MAY
FALSELY APPEAR CONGESTED

27. 3 MAIN FACTORS DETERMINE THE
TECHNICAL QUALITY OF RADIOGRAPH
• Inspiration
• Peneration
• Rotation
