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 with soft tissue, such as pneumonia or breast cancer.
If you have a x-ray, you will be asked to lie on a table or stand against a surface so that the part of your body being x-rayed is between the x-ray tube and the photographic plate.
An x-ray is usually carried out by a radiographer, a healthcare professional who specialises in using imaging technology, such as x-rays and ultrasound scanners.
