What is PETCT and how does it work

A PET scan (also called positron emission tomography and PET/CT) is a nuclear medical imaging technique that evaluates the metabolic activity of the cells. The scan can help visualize blood flow, oxygen use, sugar usage to detect abnormalities including heart problems, brain disorders, and detect cancer, staging and prognosis. This imaging methodology has the edge over other CT scans and MRIs since it can show metabolic changes occurring at the cellular level in an organ or tissue. PET-CT scan has become an indispensable tool for ensuring the correct treatment of patients and reliable diagnostics. In this technique, a small amount of a radioactive tracer is injected into a vein, and it travels through the bloodstream, where it is taken up by cells that are using more energy than normal. The scanner detects the uptake of the tracer and these cells show up as "hot spots" on the PET scan. The resulting images provide both structural and functional information about the body's internal organs and tissues. There are a number of diagnostic scan facilities in Delhi-NCR which offer the whole body PET CT facility.
