Fluid in alveolar spaces causing peripheral opacities
Kerley A lines: long, unbranched lines extending to the hilum
Kerley B lines: short, horizontal lines at the costophrenic angles
Diffuse soft, reticular form due to interstitial fluid
Which statement correctly differentiates inadequate inspiration from underpenetration on a chest X-ray?
Inadequate inspiration makes vertebral bodies invisible through the heart; underpenetration elevates the diaphragm
Inadequate inspiration elevates the diaphragm and crowds vascular markings; underpenetration makes mediastinal structures appear overly white
Both result in excessive lung darkness
Both only affect clavicle symmetry
Which structure is located in the middle mediastinum and is commonly visible as the central silhouette on a chest radiograph?
Thymus
Heart
Thoracic aorta
Vertebral bodies
On a standard posteroanterior (PA) chest X-ray, which measurement is used to estimate cardiac size?
Cardiothoracic ratio (CTR)
Cardiopulmonary index
Left ventricular ejection fraction
Pulmonary capillary wedge pressure
Which statement best describes how to calculate the cardiothoracic ratio (CTR) on a PA chest radiograph?
Sum of the maximal right and left cardiac silhouettes divided by the maximal internal thoracic diameter
Maximal cardiac height divided by lung height
Left ventricular diameter divided by right ventricular diameter
Cardiac area divided by thoracic area
Which CTR value is generally considered the upper limit of normal on a PA chest X-ray in adults?
>0.60
≤0.50
≤0.40
Between 0.55 and 0.65
Which view best complements the PA chest X-ray to assess cardiac chamber enlargement and anterior–posterior relationships?
Apical view
Lateral chest X-ray
Oblique chest X-ray
Supine anteroposterior (AP) view
In left atrial enlargement, which radiographic sign is classically expected on a PA chest X-ray?
Splaying of the carinal angle with double density along the right heart border
Marked bulge of the main pulmonary artery segment
Increased convexity of the right heart border alone
Elevation of the diaphragm
Which feature on lateral chest X-ray supports left atrial enlargement?
Posterior displacement of the esophagus by a barium swallow
Anterior displacement of the heart
Increased retrosternal air space
Diaphragmatic flattening
