Stаndаrd Chest X-rаy views  Prоjectiоns PA prоjection the posteroanterior (PA) view is the standard frontal chest projection the x-ray beam traverses the patient from posterior to anterior it is performed standing and in full inspiration with the patient hugging the detector to pull the scapulae laterally it is the best general radiographic technique to examine the lungs, bony thoracic cavity, mediastinum and great vessels advantages: technically excellent visualization of the mediastinum and lungs, with accurate assessment of heart size disadvantages: patient must be able to stand erect Lateral projection the lateral view of the chest is usually performed erect left lateral and labeled with the side closest to the cassette a paravertebral gutter technique involves rotating the right side 5-10° anterior (RAO) to align the posterior ribs along the divergent beam it allows for localization of suspected chest pathology when assessed in conjunction with a PA view examines the retrosternal and retrocardiac spaces it allows assessment of the posterior costophrenic recesses salient points gastric bubble is under the left hemidiaphragm; left hemidiaphragm is less distinct anteriorly due to the cardiac silhouette right hemidiaphragm appears more complete consider which side is closest to the image receptor (IR) i.e. a left or right lateral. The side furthest away from the IR may present manification the radiation dose from a lateral chest radiograph is substantially higher than that of a PA projection and should probably not be routinely performed for this reason
