Risks of gamma ray imaging
WebRadiation therapy uses high-energy particles or waves, such as x-rays, gamma rays, electron beams, or protons, to destroy or damage cancer cells. Your cells normally grow and divide to form new cells. But cancer cells grow and divide faster than most normal cells. Radiation works by making small breaks in the DNA inside cells. WebX-rays and gamma rays can cause a number of other problems besides cancer. What problems occur depends on factors such as the radiation dose, the timing of the …

WebCOMMUNICATING RADIATION RISKS IN PAEDIATRIC IMAGING The use of ionizing radiation in paediatric imaging saves lives and in many cases prevents the need for more invasive procedures. While every day applications of X-rays for medical imaging help millions of patients worldwide, inappropriate use may result in unnecessary and preventable WebA special camera detects gamma ray emissions from the radiotracer. The camera and a computer produce pictures and supply molecular information. Many imaging centers combine nuclear medicine images with computed tomography (CT) or magnetic resonance imaging (MRI) to produce special views. Doctors call this image fusion or co-registration.
