Positron Emission Tomography/Computed Tomography- PET/CT

Positron emission tomography scan is called as a PET scan and it is a type of test that may be used in cancer treatment and can be done along with a CT scan. It uses small amounts of radioactive materials which are known as radiotracers and radiopharmaceuticals, a special camera and a computer to evaluate organ and tissue functions. By identifying changes at the cellular level, PET may identified the early onset of disease before other imaging tests can. Nuclear medicine imaging procedures are non-invasive. With the exception of intravenous injections, they are usually painless. These tests use radioactive materials to evaluate medical conditions.
