Silhouette sign
This is a very important sign. It enables us to find subtle pathology and to locate it within the chest.
The loss of the normal silhouette of a structure is called the silhouette sign.

Here an example to explain the silhouette sign:
The heart is located anteriorly in the chest and it is bordered by the lingula of the left lung.
The difference in density between the heart and the air in the lung enables us to see the silhouette of the left ventricle.
When there is something in the lingula with the same 'water density' as the heart, the normal silhouette will be lost
(blue arrow).

When there is a pneumonia in the left lower lobe, which is located more posteriorly in the chest, the left ventricle will
(still be bordered by air in the lingula and we will still see the silhouette of the heart (red arrow
see ilms

The PA-film shows a silhouette sign of the left heart border.
Even without looking at the lateral film, we know, that the pathology must be located anteriorly in the left lung.
This was a consolidation due to a pneumonia caused by Sterptococcus pneumoniae.

Hidden areas
There are some areas that need special attention, because pathology in these areas can easily be overlooked:

apical zones
hilar zones
retrocardial zone
zone below the dome of diaphragm
These areas are also known as the hidden areas.

Notice that there is quite some lung volume below the dome of the diaphragm, which will need your attention
(arrow).

etc.......

System for looking at a CXR
Opening – say what it is! (e.g. this is a plain CXR!). Check it is the right patient, and the right date. Check it is also the right orientation. Check whether it is PA or AP. On an AP CXR the heart often appears larger than it is – so you can’t really comment on the heart size in these examples.

Check the exposure:
In a normal exposure, you should be able to just see the vertebrae through the heart.
If it is over exposed, it will be too dark
If it is underexposed, it will generally be to pale

A – Airway – is it deviated?
B – Bones – look for fractures, notches, dislocations
C – Cardiac – is the heart enlarged (greater then ½ the width of the chest; the cardiothoracic ratio)
D – Diaphragm – is there air under the diaphragm, is the diaphragm raised? The phrenic nerve innervates the diaphragm. ‘C3, C4, C5 keeps the diaphragm alive’
E – Extrathoracic – air under the diaphragm, shoulder joints, air under the skin (surgical emphysema)
F – Fields (lung!) – any masses? Consolidation? Vascular markings? Collapse?
