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 carried out by a radiographer, a professional who specialises in using imaging technology, such as X-rays and ultrasound scanners.

An ultrasound scan is a procedure that uses high-frequency sound waves to create an image of part of the inside of the body.
An ultrasound scan can be used to monitor an unborn baby, diagnose a condition, or guide a surgeon during certain procedures.
