An X-ray is a quick and painless procedure commonly used to produce images of the inside of the body. It's a very effective way of looking at the bones and can be used to help detect a range of conditions. X-rays are usually carried out in hospital X-ray departments by trained specialists called radiographers, although they can also be done by ...

Almost as soon as X-rays were discovered they were used in medical imaging. An X-ray machine is used to produce radiation which passes through your body to create an image. Different parts of your body absorb the X-rays in different amounts. Soft tissue and lungs absorb less X-rays than teeth and bones, so they look darker on X-ray images. Teeth an...
Dental radiography
This is the most common type of X-ray examination. Millions of dental X-rays are taken every year in the UK. Dental X-rays are used to diagnose disease in the mouth such as, tooth decay or gum disease. They are also used to plan treatments and monitor the health of your teeth.
General radiography
Uses X-rays to produce 2D images of the inside of your body. X-ray examinations help to diagnose conditions such as chest infections and look for broken or damaged bones. X-rays are also used in scans to monitor bone density (DXA).
Fluoroscopy
Uses X-rays to produce moving images of parts of your body which can be displayed on a screen. This is used to diagnose and monitor conditions such as your digestive system, blood flow (cardiovascular system) and urinary system. Depending on the type of examination, a dye that shows up on X-ray might be used, this may be injected or swallowed.
Uses a small amount of a radioactive substance that is usually injected into a vein (or it is swallowed or inhaled). The scanner will detect this low-level radioactivity coming out of your body and will build up images. These images show how your body is functioning. They are used to diagnose, aid treatment and monitor a wide range of diseases and ...
These are types of imaging that do not use X-rays or radioactive substances. They can be used to diagnose a range of conditions but cannot be used for everything. The imaging specialist will always consider these types of imaging if they are an option for you.
For some examinations we will need to know if you may be pregnant or breastfeeding. This is to make sure that any radiation risk to the foetus or baby is kept as low as possible. We don’t always need to ask. It will depend on the examination you are having if you are asked whether you are pregnant or breastfeeding. When the benefit to you clearly o...
Everything we do in our daily lives carries some level of risk. We tend to regard activities as being ‘safe’ when the risk of something unpleasant or unwanted happening falls below a certain level. The lower the level of risk, the ‘safer’ the activity is seen to be. People judge risk on both how likely an event is and how we would feel if it happen...
We know from studying people who have been exposed to high doses of radiation that this can increase their chances of developing cancer much later in life. However, the amounts of radiation used in medical imaging are very small and have very low risks. Any exposure to radiation from medical imaging is kept as low as possible to reduce the risks. E...
We know many people develop cancer, in fact about 1 in 2 (50%) of us will get cancer in our lifetime. The chances of any of us developing cancer are affected by all sorts of things, such as our genes, exposure to smoke, diet, weight, and alcohol intake. We have tried to estimate how much the radiation from each examination will increase your chance...

Feb 20, 2024 · X-rays, formally referred to as radiographs, are common imaging procedures ordered by healthcare providers and dentists. X-ray machines pass x-ray beams (a form of ionizing radiation) through a part of the body to produce images. These images allow healthcare providers and dentists to see if there are problems, like a broken bone or a cavity.
The main risk from having X-rays is an increase in the risk of getting a cancer in the future. This risk is thought to be very small. In the general population around half (50%) of people will get cancer at some point in their lifetime. The additional risk from having an X-ray is between 1 in a million (0.0001%) for low dose examinations, and 1 ...
