An X-ray is a widely used diagnostic test to examine the inside of the body. X-rays are a very effective way of detecting problems with bones, such as fractures. They can also often identify problems such as chest infections.
An X-ray is usually carried out in hospital by a radiographe , a healthcare professional who specialises in using imaging technology, such as X-rays and ultrasound scanners.
