CXR Interpretation

Views

PA: Preferred view

Lat: Helps delineate and localize masses, lesions or consolidation – esp if they are obscured by heart and diaphragm

ÂP: Magnifies heart and mediastinum

Associated with rotational artefact

Expiratory: helpful for small pneumothroax / gas trapping with FB

Name and DOB

Date of radiograph

Projection

Posture

Adequacy of exposure – easily visible mid-thoracic IV spaces

Degree of inspiration – diaphragm at levels of 8th -11th ribs posteriorly

5th - 6th ribs anteriorly

Degree of rotation – central spinous processes of thoracic vertebrae, equidistant from

medial ends of clavicles

Trachea – central; slight deviation to R as crosses aortic arch

Pushed away: large pleural effusion

large/tension pneumothorax

aortic aneurysm

mediastinal mass

Pulled towards: collapse

Consolidation

pul fibrosis

lobectomy, pneumonectomy

Superior mediastinum – width ................
