X-Ray - Digital Radiography

An X-ray is a quick and painless procedure that produces images of the internal structures of the body, specially the bones.In this procedure, X-rays beams pass through the body. These beams are absorbed in different amounts depending on the density of the material they pass through. Metal and bones are dense materials that show up as white on an X-ray report. The air in the lungs show up as black. Fat and muscles appear as different shades of grey.

Sometimes, a contrast medium – such as barium or iodine are introduced in the body to provide a better detail on the images. An X-ray technology is used to examine the different parts of the body. It is used to detect fractures and infections in the bones and teeth. It is also used to detect arthritis, dental decay or osteoporosis.

An X-ray can also reveal bone tumors. An X-ray is used to detect problems in the chest such as lung infections or conditions, enlarged heart, blocked blood vessels or breast cancer. It is used to also detect abdominal problems such as digestive tract problems or swallowed items.

There are some risks associated with x-rays as the body undergoes radiation exposure. Sensitivity to radiation depends on the age, with children being more sensitive than adults.
