What is PET-CT Scan?
PET, or Positron Emission Tomography is a type of nuclear medicine imaging. PET scan measures important body functions such as oxygen use, blood flow, glucose metabolism etc. This measurement equipped the doctors in evaluating the organs and tissues performance.
CT, or Computed Tomography is used to produce multiple images inside the body and provide excellent anatomic information.
Today, most of the PET scans are superimposed with CT using radiotracers to provide more accurate and comprehensive information on the abnormal activity and function of cells. Other than detecting cancer earliest and accurately, PET-CT can also distinguish malignant and benign tumors observing the progress of cancer treatment as well as prognosis.
