X-rays for Diagnostic imaging

An X-ray is a painless and rapid diagnostic imaging test which employs low bursts of ionising radiation to generate images of internal body parts. This test enables doctors to examine the heart, lungs, bones, airways, and blood vessels.

X-rays, a form of radiation similar to light or radio waves, can traverse through most objects, including the human body. However, some parts of the body absorb varying amounts of X-rays, with bones absorbing significantly more than soft tissue.

In order to produce an image of the inside of the body, an X-ray machine emits brief bursts of X-rays onto the patient's body, which then penetrate through the body and form an image upon striking a unique image recording plate positioned on the opposite side of the patient.

The image portrays the internal structures of the chest, with diverse tissues and organs appearing in distinct shades. For instance, bones, like the ribs, will emerge as white as they obstruct and absorb most of the X-rays, whereas soft tissue, like the lungs, will display varying shades of grey, and air will appear black.

Before undergoing an X-ray, no special preparation is necessary, although you may be required to remove any jewellery, glasses, particular dental appliances, and clothes with metallic components. Typically, X-rays are not conducted on pregnant women to avoid exposing the foetus to radiation. Therefore, it is essential to notify your doctor if there is a possibility of pregnancy.
