PET-CT - Introduction

PET

Positron Emission Tomography - Computed Tomography (PET-CT) is a sophisticated hybrid imaging technique that allows the visualization of human anatomy and metabolic activity by using x-ray and a small amount of short-lived positron emitting radiopharmaceuticals.

It is a non-invasive technology that can routinely examine the whole body in one single examination. PET-CT is playing a major role in oncology. In particularly, it helps doctors to detect and grade tumors, to follow-up treatment response and detect recurrent cancer.
