Positron Emission Tomography (PET) Scan

  • What is Positron Emission Tomography (PET) Scan?

    PET is an advanced medical imaging examination that provides detailed information on the function of an organ or system in your body. PET scans are commonly used to evaluate and diagnose cancers, neurological (brain) disorders, and cardiovascular (heart) diseases.

    During a PET scan, a radioactive tracer is injected and images of your body are recorded using a PET scanner. A camera detects the emissions resulting from the injected radioactive tracer, and a computer then creates multi-dimensional images of the part of your body being examined. The injected radiotracers usually accumulate in diseased tissues more than healthier tissues. Most PET scanners are combined with computerised tomography (CT) scans. This further allows the structural information provided by CT images to be combined with the PET’s functional information.

  • A PET scan is mainly used to detect and monitor conditions including cancers, neurological (brain) disorders, and cardiovascular (heart-related) diseases. It can detect cancers before they can be detected using other imaging techniques (such as CT and MRI scans). It also enables your doctor to determine whether and where a cancer is spreading to other parts of the body.

    A PET scan can assist in the planning of surgery for epileptic seizures by showing which part of the brain is responsible for your epilepsy. It is also used to assess Alzheimer’s Disease and Parkinson’s Disease because the resulting images can pinpoint areas of the brain that are not functioning normally. Early detection of these neurological disorders lead to more effective treatment.
