What Is Pet Scan
SlideMake.com
,Introduction to PET Scan
• A PET scan, or Positron Emission Tomography scan, is a
medical imaging technique used to visualize metabolic
processes in the body.
• It helps doctors detect and monitor diseases such as
cancer, heart disease, and brain disorders.
• The scan provides detailed images by measuring the
distribution of radioactive tracers injected into the patient.
,How a PET Scan Works
• A small amount of radioactive material, called a tracer, is
introduced into the body, usually through injection.
• The tracer emits positrons, which are detected by the PET
scanner to create images of the targeted organs or tissues.
• The scan shows areas of high or low metabolic activity,
indicating normal or abnormal function.
,Uses of PET Scan
• PET scans are primarily used in oncology to detect tumors
and evaluate their response to treatment.
• They are also valuable in neurology for diagnosing
conditions like Alzheimer’s disease and epilepsy.
• Cardiologists use PET scans to assess blood flow and detect
areas of reduced heart function.
, Advantages and Limitations
• PET scans provide functional information that other imaging
techniques, like MRI or CT, may not reveal.
• The procedure is non-invasive and can help in early
diagnosis of various diseases.
• However, PET scans involve exposure to a small amount of
radiation and may not be suitable for pregnant women.
