Positioning for a PA chest x-ray Normal lateral chest radiograph. Different views (also known as projections) of the chest can be obtained by changing the relative orientation of the body and the direction of the x-ray beam. The most common views are posteroanterior, anteroposterior, and lateral. In a posteroanterior (PA) view, the x-ray source ...
A posterior-anterior (PA) chest X-ray is the standard view used; other views (lateral or lordotic) or CT scans may be necessary. [citation needed] In active pulmonary TB, infiltrates or consolidations and/or cavities are often seen in the upper lungs with or without mediastinal or hilar lymphadenopathy. [1] However, lesions may appear anywhere ...
Chest x-ray is the first test done to confirm an excess of pleural fluid. The lateral upright chest x-ray should be examined when a pleural effusion is suspected. In an upright x-ray, 75 mL of fluid blunts the posterior costophrenic angle. Blunting of the lateral costophrenic angle usually requires about 175 mL but may take as much as 500 mL.
Obliques 20 degrees from lateral may be ordered to better visualize the zygapophysial joint. Lumbar Spine - AP and Lateral +/- L5/S1 view in the UK, with obliques and Flexion and Extension requests being rare. [15] In the US, basic projections include an AP, two Obliques, a Lateral, and a Lateral L5-S1 spot to better visualize the L5-S1 interspace.
A) Normal chest radiograph; B) Q fever pneumonia affecting the right lower and middle lobes. Note the loss of the normal radiographic silhouette (contour) between the affected lung and its right heart border as well as between the affected lung and its right diaphragm border. This phenomenon is called the silhouette sign: Differential diagnosis
However, lesions may appear anywhere in the lungs. In disseminated TB a pattern of many tiny nodules throughout the lung fields is common - the so-called miliary TB. In HIV and other immunosuppressed persons, any abnormality may indicate TB or the chest X-ray may even appear entirely normal. [citation needed]
Tram tracks are caused by bronchial wall thickening, and can be detected on a lateral chest X-ray. [1] ... Mobile view; Search. Search. Toggle the table of contents.
Scoliosis, abnormal lateral curvature of the spine [7] Barrel chest, bulging out of the chest wall; normal in children; typical of hyperinflation seen in chronic obstructive pulmonary disease (COPD) [8] Pectus excavatum, sternum sunken into the chest [9] Pectus carinatum, sternum protruding from the chest [10]
