2. Introduction
• Most of the chest x-rays you will see
will be normal
• In order to recognise abnormality, you
need to know what a normal CXR looks
like
The CXR on the next slide is normal. How
would you interpret it?
3.
4. General Principles
• Have a systematic approach
• Interpret the CXR in conjunction with
the clinical findings
• Always compare with previous CXR if
available to assess for change
• Ask yourself “does my interpretation
make sense?”
9. •Heart
Systematic Approach
•Occupies up to 50% of
the maximum internal
thoracic diameter on a
standard PA erect view
•Cannot comment on
heart size on AP view
because of magnification
of heart
13. •Diaphragm
Systematic Approach
•Both diaphragms
should form a sharp
margin with the lateral
chest wall
•Both diaphragm
contours should be
clearly visible medially
to the spine
