1. Abnormal chest xrays……………….

2. Basic Chest X-Ray Interpretation

3. X-rays- describe radiation which is part of the
spectrum which includes visible light, gamma rays and cosmic radiation.
Unlike visible light, radiation passes through stuff.
When you shine a beam of X-Ray at a person
and put a film on the other side of them a shadow is produced of the inside of their body.

4. Different tissues in our body absorb X-rays at different extents:
Bone- high absorption (white)
Tissue- somewhere in the middle absorption (grey)
Air- low absorption (black)

5. General Principles
Read X-Rays yourself Be systematic Be aware of common artifacts Serially compare Observe symmetry Believe you missed a finding

6. CXR Interpretation Format
Check info on CXR Evaluate technique(rotation, penetration, lung expansion) Examine soft tissues and bones Find Alien equiptment Evaluate structures(diaphragms, trachea, hilum, heart shadows) Evaluate lung pathology last
