Positron emission tomography (PET/CT) is currently the most advanced medical imaging technology.

PET evaluates the metabolic activity of cells, particularly the metabolism of glucose.

PET uses a molecule similar to glucose, FDG (fluorodeoxyglucose), which contains fluorine-18, a positron emitter that is captured by glucose-savvy cancer cells.

A radioactive substance (18FDG) is administered to the patient. The patient is then placed in front of a camera which allows imaging of the distribution of this substance in his body.

PET, combined with 16-detector computerized axial tomography (PET/CT), also provides high-definition anatomical information. The reading of the exam is done by a nuclear medicine specialist.

  • Allows early diagnosis of cancer, often before it leads to anatomical changes.
  • Allows assessment of the extent and the precise stage of the cancer. Essential in choosing the best treatment. Sometimes helps to avoid unnecessary surgery.
  • Allows rapid evaluation of the patient's response to the treatment and its success.
  • Identifies distant, often hidden, metastases that can change the course of the disease and the patient's treatment.
  • In some cases, a single examination (PET/CT) can answer many clinical questions that usually require several other types of exams.
  • They mainly concern the diagnosis and/or monitoring of cancer cases, including:
  • Lung cancer and pulmonary nodules
  • Lymphoma
  • Cancer of the head and neck (ORL)
  • Colorectal cancer
  • Esophageal cancer
  • Pancreatic cancer
  • Melanoma
  • Thyroid cancer
  • Breast cancer
  • Testicular cancer 
  • Uterine/ovarian cancer
  • Central nervous system (Alzheimer's disease, epilepsy, etc.)
  • Cardiac system (viability of the heart muscle, etc.)

Upon arrival, our staff welcomes you to check-in for your exam on the third floor.

You will be seated comfortably with a warm blanket. After installation of a venous access by the technologist, he/she will then inject the FDG (fluorodeoxyglucose) which contains fluorine-18. You will rest for a period of 30-60 minutes before the images are taken. Thereafter, images will be taken using the PET-CT system. The procedure lasts about 40 minutes. After checking the images, the technician will give you a CD that you can give to your doctor.


Since the exam is in the afternoon, a fast of six hours before the examination is required.

You can drink water at all times.

Do not do strenuous exercise in the 24 hours before the examination.

For patients with diabetes, be sure to maintain good control of your blood sugar level.

Upon arrival, our staff welcomes you to check-in for your exam on the third floor.
