There are generally four types of technology used to carry out different types of medical imaging procedures:. The radiation exposure a patient receives will depend on the type of examination and the purpose of the imaging study. Generally, plain X-rays, mammography and fluoroscopy give a lower radiation dose than CT, but complex procedures using fluoroscopy can result in doses similar to extensive CT examinations.

Ultrasound and MRI do not use ionising radiation. Because children are more sensitive to the effects of ionising radiation it is important, where possible, to use tests that do not require ionising radiation i. These risks are difficult to accurately measure, but it has been shown that the risk of developing cancer is slightly increased if you have been exposed to additional ionising radiation above background levels.

The risks are not the same for all people; females are slightly more sensitive to the effects of ionising radiation compared with males. Children are also more sensitive, as the cells that make up their growing tissues and organs are dividing more rapidly. Children also live longer, so the effects of radiation have more time to become visible. Some people have genetic differences that predispose them to the effects of ionising radiation. There are other risks from high exposures to ionising radiation, but these are not expected at the dose levels used in diagnostic imaging.

The increased risk is small, and usually less than the risk from not identifying or treating a disease or condition properly. It is important to make sure that every test has a definite benefit to balance the small radiation risk of the test.

If you are referred for a CT scan or other test involving ionising radiation, it is important that you discuss the relative risks and benefits with your referring doctor so that you understand how you will benefit from having the study. All operators of an X-ray machine including CT have been trained to use only enough X-rays to provide quality pictures for the specialist. The dose of ionising radiation is therefore kept to a minimum. The purpose of diagnostic radiology is to provide the radiologist or nuclear medicine specialist specialist doctors with images of sufficiently high quality, so that they can report the results of the test to your doctor to assist in understanding and explaining your medical problem or symptom, and confirm either the presence or absence of disease or injury.

It is important that any request for an imaging test is provided by your doctor, in consultation with you. It is your own doctor who will be able to make an assessment of whether the benefits of the X-ray procedure outweigh any possible risks. The radiologist or nuclear medicine specialist supervising the procedure will also assess if it is the most appropriate test, taking into account the information your doctor has written on the request form together with your medical history. Your decision should be made in close consultation with your referring doctor.

Ask your doctor about the procedure and how it will help to provide information about your symptoms or the presence of disease or injury. Ask your doctor about the risks of the procedure and what the risks would be of not having the procedure; that is, if your doctor needs the information in order to identify and plan the most appropriate treatment. Although there is a small risk of harm from ionising radiation, there could be a greater risk of not having the information; for example, failure to detect potentially serious disease that could be easily treated at an early stage, but is harder to treat or is incurable if detected later.

Discuss any concerns with your doctor, and access reputable websites to find out information. You might also be able to obtain information from the hospital or private practice where your doctor has referred you for the procedure. It might also be as beneficial to you to confirm the absence of disease or injury as it is to confirm its presence. MRI and ultrasound studies are usually used in preference to other imaging tests when it is possible to do so.
