Guide To Positron Emission Tomography Scans (PET Scans)

A positron emission tomography scan (PET scan) is a type of imaging test used for diagnosing numerous diseases in an individual's body. This scan highlights parts of the body where there are increased rates of certain chemical activities. A PET scan can tell a patient's doctor about how their body uses oxygen, how their body processes glucose, and about their blood flow. These scans can give a patient's doctor insight into problems occurring at the cellular level. This helps them identify and evaluate certain complex systemic conditions and diseases, including heart problems and brain disorders.
