CHEST AND THORAX

• ASPIRATION: radiodense or radiopaque outline
• ATELECTASIS: radiodense lung regions with shift of heart and trachea in severe cases
• BRONCHIECTASIS: radiodense lower lungs
• BRONCHITIS: Hyperinflation and dominant lung markings of LL
• CYSTIC FIBROSIS: increased radiodense in specific lung regions
• EMPHYSEMA: increased lung dimension, barrel chest,flatted diaphragm, elongated heart shadow, lung fields appear very radiolucent
• PNEUMONIA: patchy infiltrate with increase radiodensity
• PNEUMOTHORAX: lung seen diaplaced from chest wall, no lung markings
• PULMONARY EDEMA: increased diffuse radiodensity in hilar regions
• PULMONARY EMBOLI: wedge-shaped opacity (Hampton’s Hump)
• TUBERCULOSIS: regions of calcification with cavitations,frequently in area of upper lobes and apices
• PECTUS CARINATUM: (Pigeon chest)

  RA: Anterior protrusion of the lower sternum and xiphoid process
• PECTUS EXCAVATUM
