General Terms, hints and tips
Hila – the left hilum is slightly higher than the right hilum.
Gas – remember don’t be confused by gas in the stomach! So gas on the left is often normal, but gas under the right hemi diaphragm is not! Also, free gas in the abdomen usually (but not always) will go to the right first, because this is higher than the left.
Blood vessels – are more extensive to the lower half of the lung than to the upper half. They sort of loop down from the heart like a droopy moustache.
Free fluids – in the pleural space – i.e. pleural effusion – may or may not have a meniscus. The fluid (as long as it is erect CXR) will be at the bottom of the lung. If the pressure of the air is high, the meniscus may be flattened.
If there isn’t a meniscus, you should question if the opacity is due to a fluid level or another cause.
Ribs – remember you can see them anteriorly and posteriorly. Generally the posterior ribs will be more horizontal, and the anterior ribs will be more diagonally.
Clavicle – to judge if the CXR is rotated or not, look at the distance between the central end of the clavicle, and the centre of the trachea. This distance should be equal on both sides
Heart – to quickly estimate if the heart is enlarged – the diameter of the heart should be roughly less than ½ the width of the chest
Aortic knob – this is the blob that the aortic arch makes on an x-ray
Vascular markings – these should not be visible in the lateral 1/3 of the lung.
Costophrenic recess – these will not be visible / will be filled in (opaque), in pleural effusion, and less commonly in consolidation.
Diaphragm – the right is higher on a normal CXR due to the liver.
Bronchial tree – the right is steeper than the left – due to the differing lobar structure. Inhaled foreign object will usually fall down the right as it is steeper.
Lung fissures – these can often be clearly seen if there is fluid – ie in pleural effusion.
Transverse fissure – separates upper and middle lobes of the lung.
Oblique fissure – separate the lower from the other two lobes – the upper and middle lobes are generally anterior, the lower lobe is generally posterior.
In Right upper lobe collapse – the transverse fissure moves upwards
Fluid and air enclosed in the same space in CXR – e.g. pleural effusion + pneumothorax = hydropneumothorax. Other examples include a fluid filled stomach, and a fluid filled abscess.

Common Diagnoses

PLEURAL EFFUSION
Meniscus
Uniformly white


:Collapsed lung
(Mediastinal shift (towards the collapse
Absent vascular markings
May appear like a squished white blob around the hila, or dense whiteness (similar to the heart) as the tissue has collapsed and taken on the density of normal tissue


:Pneumothorax
Mediastinal shift (away from the affected lung)
Absent vascular markings
But also note that in the pneumothorax the lung will collapse because it is being pushed from the outside


:Heart failure
Enlarged heart
Bilateral fluid in the alveoli (i.e lots of whiteness all over the place!) – pulmonary oedema
This will look similar too ARDS – acute respiratory distress syndrome
Also looks similar to pneumonia – but pneumonia will tend to be more localised.


-:Malignancy
:Metastasis
Round lesions
Several lesions
Well demarcated
'cannon ball lesions’
Lesions of 2-3cm diameter usually
