A chest x-ray produces images of the heart, lungs, airways, blood vessels and the bones of the spine and chest
An X-ray of the chest is a safe and painless test to visualize
the structures of the chest wall which includes the collar bone, breastbone,
ribs, shoulder blade and surrounding muscles. It also helps to visualize the
internal organs of the chest which includes the lungs, airways, heart, food
pipe and diaphragm. The image is recorded on a special X-ray film using small
amount of radiation. The X-ray image is black and white. Dense structures such
as the bones, appear white and softer body tissues, such as the skin and
muscles appear darker. The actual exposure time to radiation is usually less
than a second, although the overall test may take 15-20 minutes.
