WHAT IS CHEST RADIOGRAPHY (CHEST X-RAY, CXR) TEST?
X-rays are passed through the chest and react on a special photographic plate. Normally the lungs are radiolucent. Bones and fluid-containing bodies such as the heart, the aorta, and any tumour or infiltrate are denser than the lungs and can be easily visualised. Chest radiographs can be performed with the client standing or sitting upright, during inhalation, and in anteroposterior, posteroanterior, and lateral views. Portable, in-bed, anteroposterior chest radiographs can be performed for clients too ill to transport to the radiology department.
