Why do I need an X-ray?
Typically, X-rays are done in order to assess or examine an area causing discomfort or pain or to ascertain whether a bone is broken after an accident or trauma, they also monitor how well a treatment is working, the body is healing and to track the progression of a disease that has been previously diagnosed, such as osteoporosis (a condition where the bones become weak and fragile).
X-rays are used to examine different parts of the body, these can include:
Teeth and bones
- Fractures and infections in the bones– these show up clearly in X-rays.
- Arthritis affecting the joints – X-rays help your doctor to detect, monitor and track progression of the conditions, noting if it is getting better or worse through comparing years of X-rays.
- Osteoporosis– this is detected and monitored through measuring bone density through special types of X-ray.
- Dental decay –involves using X-rays to check for cavities in the teeth.
- Bone cancer– X-rays reveal bone tumours.
- Digestive tract issues –are detected using a barium enema or liquid, which is a swallow test that gives a visual representation of the digestive tract through the use of an X-ray. The liquid is swallowed or delivered in an enema (injecting the liquid into the rectum) and passed through the body to allow areas with an issue to be detected.
- Items swallowed – if something has been swallowed by accident that the body cannot digest, which occurs in cases with children regularly, an X-ray can detect the item and its position in the digestive tract.
- Lung conditions – X-rays can detect evidence of tuberculosis, pneumonia and lung cancer.
- Breast cancer – using a mammogram, which is a special type of X-ray test that is used to assess the tissue of the breast and detect any abnormalities such as lumps that could possibly be cancerous.
- Enlarged heart – X-rays are able to clearly detect any signs of congestive heart failure.
- Blocked blood vessels – these are detected through injecting a material that is able to show up clearly on an X-ray intravenously (into your vein), known as a contrast material. It normally contains iodine, which highlights specific areas of the circulatory system to clearly appear on the X-ray. If you are allergic to iodine it is important to tell your doctor and radiographer (the person performing the X-ray) so that an alternative contrast can be used.
