Radiation Exposure

A PET scan is a medical imaging procedure that uses a small amount of radioactive material, called a tracer, to help visualize the internal organs and tissues of the body. PET stands for positron emission tomography, which is a type of imaging technique that uses a special camera to detect the radioactive tracer in the body. How Does a PET Scan Work? During a PET scan, the patient is injected with a small amount of radioactive material, usually through a vein in the arm....

The PET scan is a medical imaging technique that is used to diagnose and monitor a wide range of diseases, from cancer to heart disease. The acronym PET stands for Positron Emission Tomography, a term that refers to the way in which the scan is performed. Unlike other imaging techniques like X-rays and CT scans, PET scans do not use ionizing radiation. Instead, they rely on the detection of small amounts of radiation emitted by a radioactive tracer that is injected into the body....
