PET and PET/CT
PET stands for Positron Emission Tomography. A PET scan demonstrates the biological function of the body, while the CT scan provides information about the body’s anatomy such as size, shape and location.
PET/CT is a combined technology. PET (positron emission tomography) provides images of what is actually happening at a cellular level and the anatomical images from CT give a detailed picture of the body's internal anatomy. Together in one image set they allow physicians to determine the extent and location of cancer within the body so the best treatment plan can be made.
Early Diagnosis and Treatment
Since PET scans show physicians images at the molecular level, they can help them detect abnormalities at a very early stage.
Alone, each imaging test has particular benefits and limitations, but by combining these two state-of the-art technologies, physicians can more accurately diagnose, localize and monitor cancer, as well as heart disease and certain brain disorders.
