PET-CT in Istanbul is available at 7 hospitals in the Voumed network.

PET-CT is an advanced hybrid imaging method that combines positron emission tomography with computed tomography in a single scan, mapping both the metabolic activity and the anatomical structure of the body at once. A small dose of a radioactive tracer, often a glucose analogue, is injected and gathers in cells that are working harder than normal, which is typical of many tumours. Because it can show where a disease is active before it changes the shape of an organ, PET-CT is one of the most valuable tools for detecting cancer, working out how far it has spread, and checking whether treatment is working.
