Diagnostic Imaging Services: PET

PET/CT Scanner

Fox Chase Cancer Center was the first institution in the Greater Philadelphia region to offer the PET/CT Scanner.

PET/CT is the combination of two advanced technologies fused together to give higher quality, more detailed images of a patient's internal anatomy and cell metabolic function.

PET stands for Positron Emission Tomography and is the computerized process of imaging high metabolic activity. Metabolic activities are the physical and chemical changes taking place in living cells, such as how cells absorb nutrition.

Cancer Types Diagnosed

  • head and neck
  • breast, lung
  • esophagus
  • colon
  • lymphoma
  • melanoma
  • certain thyroid cancers.

CT, or Computerized Tomography, uses X-ray images to illustrate the anatomical structures of the body. The fusion of these two technologies creates the revolutionary PET/CT unit, which aids the physician in detecting tumors.

PET/CT is especially useful for accurate diagnosis and staging of cancers of the head and neck, breast, lung, esophagus, colon, lymphoma, melanoma and certain thyroid cancers.

Advantages of PET/CT fusion:

  • Detecting small tumors, allowing for diagnosis of very early cancers
  • Improving the precision of cancer staging prior to surgery or other cancer treatment
  • Determining if a cancer has recurred (come back) or if a lesion is scar tissue from surgery
  • Eliminating unnecessary invasive exams or surgeries

More benefits of PET:

  • Telling the difference between benign masses and malignant (cancerous) ones
  • Detecting distant metastases (the cancer spreading)
  • Staging patients for known cancers
  • Helping in radiation treatment planning
  • Checking to see if a cancer is responding to treatment
