Shadowing in the right lower zone with loss of the right hemidiaphragm
Right lower lobe
Reduced definition of the right heart border is typically associated with ___________ consolidation
Right middle lobe
Reduced definition of the left heart border is typically associated with _________ consolidation
Lingular
Pushing of the trachea: ?
Large pleural effusion or tension pneumothorax
Pulling of the trachea: ?
Consolidation with associated lobar collapse
Bilateral symmetrical enlargement on a CXR is typically associated with..
Sarcoidosis
Unilateral/asymmetrical hilar enlargement may be due to..
Malignancy
The pleura are not usually visible in healthy individuals. If the pleura are visible it indicates the presence of..
Mesothelioma (pleural thickening)
The _______ makes up most of the right heart border
Right atrium
The ________ makes up most of the left heart border
Left ventricle
____________ can indicate the presence of fluid or consolidation in the area
Costophrenic blunting
Costophrenic blunting can develop secondary to lung hyperinflation as a result of diaphragmatic flattening and subsequent loss of the acute angle due to…
COPD
Loss of aortopulmonary window occurs as a result of..
Mediastinal lymphadenopathy (e.g. malignancy)

LLL collapse
Luftsichel sign
LUL collapse
Pneumoperitoneum - perforation (peptic ulcer, diverticulitis etc)
Criteria for correct NG tube placement
CXR view is adequate (upper oesophagus down to below the diaphragm)
NG tube remains in the midline down to the level of the diaphragm
NG tube bisects the carina
Tip of the NG tube is clearly visible and below the left hemidiaphragm
Tip of the NG tube is 10 cm beyond the GOJ and therefore is likely to be within the stomach (pH <5)
Imagie quality interpretation RIPE
RIPE
Rotation - medial aspect of each clavicle should be equidistant from the spinous processes. Spinous processes should also be vertically aligned
Inspiration - 5-6 anterior ribs, lung apices, both costophrenic angles and the lateral rib edges should be visible
Projection - if the scapulae are not projected within the chest, it’s PA)
Exposure - left hemidiaphragm should be visible to the spine, and the vertebrae should be visible behind the heart
ABCDE approach
Airway: trachea, carina, bronchi and hilar structures
Breathing: lungs and pleura
Cardiac: heart size and borders
Diaphragm: including assessment of costophrenic angles
Everything else: mediastinal contours, bones, soft tissues, tubes, valves, pacemakers and review areas
CXR findings in HF
A: alveolar oedema (perihilar/bat-wing opacification)
B: Kerley B lines
C: cardiomegaly (cardiothoracic ratio >50%) – may be difficult to assess on an AP film
D: dilated upper lobe vessels
E: effusions (i.e. pleural effusions – blunted costophrenic angles with meniscus sign)
Hyperinflated lung
Bilateral symmetrical Attenuated pulmonary vasculature
Long tubular heart
Flattening of diaphragm
COPD
Bilateral infiltrates and air bronchograms with a perihilar distribution
