What is a PET-CT Scan?

PET‐CT technology is a major development in cancer detection and an accurate and cost effective way to monitor response to therapy.

PET stands for “Positron Emission Tomography”.

It is an advanced imaging technique that uses very small amounts of radioactive tracer called “FDG” (similar to sugar), to produce images showing how your body is functioning.

You may already be familiar with CT (Computed Tomography), which uses x-rays to produce pictures showing structures in the body.

By combining these two techniques in one scanner, a PET‐CT scan provides important information that can help your doctor plan the best treatment for you.
