An X-ray (also known in many languages as Röntgen radiation) is a form of high-energy electromagnetic radiation with a wavelength shorter than those of ultraviolet rays and longer than those of gamma rays.

If you have an x-ray exam that includes tissues or organs that are more sensitive to radiation, your effective dose will be higher. Effective dose allows your doctor to evaluate your risk and compare it to common, everyday sources of exposure, such as natural background radiation.

In large doses, radiation can cause serious tissue damage and increase a person’s risk of later developing cancer. The low doses of radiation used for imaging tests might increase a person’s cancer risk slightly, but it’s important to put this risk into perspective.

2021年9月30日 · Patients want to know if radiation from mammograms, bone density tests, computed tomography (CT) scans, and so forth will increase their risk of developing cancer. For most women, there's very little risk from routine x-ray imaging such as …

2023年7月13日 · X-rays are a type of radiation that can generate images of tissues and structures inside the body. Although a vital imaging tool, X-rays pose risks and can cause alterations in DNA. X-rays...

4 天之前 · X-ray, electromagnetic radiation of extremely short wavelength and high frequency, with wavelengths ranging from about 10^-8 to 10^-12 metre. The passage of X-rays through materials, including biological tissue, can be recorded.

X-rays are a form of electromagnetic radiation, similar to visible light. Unlike light, however, x-rays have higher energy and can pass through most objects, including the body. Medical x-rays are used to generate images of tissues and structures inside the body.

2024年2月20日 · 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.

An X-ray is a type of medical imaging that uses radiation to take pictures of the inside of your body. We often think of X-rays as something providers use to diagnose broken bones or look at your teeth .

Computed tomography (CT), fluoroscopy, and radiography ("conventional X-ray" including mammography) all use ionizing radiation to generate images of the body. Ionizing radiation is a form of...
