Having an examination

Diabetic patients

Dear Sir/Madam,

You are going to undergo 18F-FDG (fluorodeoxyglucose) Positron Emission Tomography (PET scan).

The tracer that will be injected into your vein is a glucose analogue.

A very small amount is injected: administration will not affect your blood glucose levels. Renal failure is not a contraindication for the examination.

Conversely, so that the examination is as sensitive as possible, in other words so that it works as well as possible, you must have an optimal blood glucose level, ideally with a fasting blood glucose level less than 2 g/l (11 mmol/l). We encourage you to check your capillary blood glucose in the days leading up to the examination and to contact your doctor in case of diabetic imbalance. Your capillary blood glucose will be checked when you arrive at the department. Excessively high blood glucose may make the examination less sensitive and, depending on the circumstances, the examination may be postponed if your blood glucose is too high.

  • Please read the recommendations regarding taking medication.
  • Please contact your doctors for more information.
