X-rays produce clear images of bone and are used to check for fractures. They are also used for teeth and joints. Chest x-rays are used to examine the heart and lungs for heart conditions or tumours in the lung. Bones can be examined using a low dose of x-ray to look for changes in the density of the tissue that may indicate a condition such as osteoporosis. Breast tissue can also be examined using a low dose of x-ray to look for tumours; this is called a mammogram.

Often, an x-ray is all that is needed to diagnose or assess the presenting symptoms. In some cases, more sophisticated imaging techniques may be needed for accurate or further assessment.
