PET CT scan

What is a PET CT scan?

A PET CT scan is a powerful scan that takes pictures of your entire body to help diagnose and stage cancer. The CT scan takes a series of images of the whole body and converts them into a 3 D shape for better understanding of the body's internal organs. The PET scan uses low-dose radiation to assess the activity of the cells. The combination of a PET scan and CT scan is called a PET CT scan. Cancers cells have much higher activity than the normal cells and hence show up better on the PET CT scan. For a PET scan in Bangalore consult the best cancer hospital near you.

What is PET?

PET is an abbreviation for Positron Emission Tomography. It uses radiation or nuclear medicine imaging to create three-dimensional colour images of the functional activities within the human body.

A Computed Tomography (CT) scan shows the structure. Combining these two scans into a single advanced PET/CT imaging technique gives detailed information about the existence or spread of disease and accurately identifies its specific location

How does PET work?

It is a procedure that involves injecting a radiotracer (radioactive glucose) into the veins of a patient's arm. The radiotracer will travel through the body and get absorbed by the tissues or organs which are to be studied. Then using high-tech machines or devices, the energy given off by the tracer is converted into a 3-D image.
