A PET-CT scan is a combination of PET (positive emissions tomography) and a CT (computerised tomography) antofagastaairportcarrental.com scans take a series of x-rays to build up a three dimensional picture. A PET scan uses low dose radiation to measure the activity of cells in different parts of their body. A PET-CT (Positron Emission Tomography Computed Tomography) is an advanced technology scan, which combines a CT and a PET scan into one. The scan uses X-ray technology together with a radioactive tracer to produce a detailed three-dimensional picture of the internal anatomy and function. It reveals information about both the structure and function of cells and tissues in the body. PET is the. PET-CT (Positron Emission Tomography and Computerised Tomography) is a scanning method that allows us to see how organs are working. PET/CT helps us identify organs or tissues that are not working normally. The body is imaged following the injection of a radioactive tracer (most commonly 18FDG; a form of slightly radioactive sugar.)
