PET/CT scan 

PET/CT scan combines the imaging power of Positron Emission Tomography, with that of Computed Tomography.  A PET scan measures important body functions such as blood flow, oxygen use, and sugar metabolism, to help doctors evaluate how well organs and tissues are functioning, while a CT scan provides excellent anatomic information by interpreting a series of images into one cohesive 3-D image of the body.

Using a PET/CT scanner, the information from these two types of imaging can be imposed onto one image, allowing for more detailed images, and more accurate diagnoses.

Some common reasons PET/CT scans are ordered:

  • detecting cancer
  • determining whether a cancer has spread in the body
  • assessing the effectiveness of a treatment plan, such as cancer therapy
  • determining if a cancer has returned after treatment
  • determining blood flow to the heart muscle
  • determining the effects of a heart attack, or myocardial infarction, on areas of the heart
  • identifying areas of the heart muscle that would benefit from a procedure such as angioplasty or coronary artery bypass surgery (in combination with a myocardial perfusion scan)
  • evaluating brain abnormalities such as tumors, memory disorders, and seizures and other central nervous system disorders
  • mapping normal human brain and heart function
