X-ray

An X-ray is commonly used to determine if there is a bone fracture. It is a quick and cost-effective method for examining hard structures, particularly bones.

How is an X-ray taken?

This imaging technique uses X-rays, which pass through the body. However, not all tissues allow the radiation to pass through equally. Bones, for example, block more radiation and therefore appear lighter on the image.

Other tissues, such as the air-filled lungs, allow radiation to pass through more easily and appear darker. With proper imaging techniques, an X-ray can provide information about bones, fluid, air, the contours of soft tissues, and materials placed during surgeries, such as prosthetic joints or screws.

The radiation emitted during an X-ray can damage DNA if the exposure is high. However, the radiation from one or a few X-rays is limited and therefore not immediately dangerous.

Not all tissues in the body are clearly visible on an X-ray. Softer tissues, for example, are better visualized on an MRI scan. Another limitation is that X-rays do not show depth, and different structures can overlap. An advantage is that taking an X-ray is quick and does not require the patient to fast.

The results are communicated through the patient’s own doctor, who will also discuss any further treatment.
