Abstract. The use of radiation in medicine is now pervasive and routine. From their crude beginnings 100 years ago, diagnostic radiology, nuclear medicine and radiation therapy have all evolved into advanced techniques, and are regarded as essential tools across all branches and specialties of medicine. The inherent properties of ionizing ...
22 Νοε 2020 · Not all medical imaging uses radiation. Ultrasonography and Magnetic resonance imaging are safe. X-ray films, Angiography/fluoroscopy, Computed tomography, Nuclear medicine (including positron emission tomography) imaging modalities are risky and should be used only when benefits outweigh the risks.
7 Ιουλ 2023 · Every day, people inhale and ingest forms of radiation from air, food and water. Today, the most common artificial sources of human exposure to radiation are X-ray machines and radiopharmaceuticals used for diagnostic or radiotherapy and other medical devices.
Exposure to radiation generally is considered harmful to the human body, but radioisotopes are highly valuable in medicine, particularly in the diagnosis and treatment of disease. Nuclear medicine uses radioactive isotopes in a variety of ways.
