About the appointment

We offer this examination at the following locations in Vienna.
  • PET-CT cancer diagnostics
  • Immediate appointments
  • Private institute

How FET works

Special tracer for the brain

Oncological brain diagnostics

Prior to surgical intervention, conclusions can already be drawn with regard to grading and the spread of tumours by means of the FET tracer. Biopsies can also be better planned and performed in a more targeted manner. The examination has also proven beneficial in case of an unclear differen­tiation based on MRI between relapse and post-therapeutic changes after surgery.

High specificity for brain tumours

The amino acid tyrosine is a natural building block of protein metabolism. Tyrosine, labelled with the radioactive isotope F‑18 (F‑18 ethyl-tyrosine) has a high specificity for the display of brain tumours and is used to differentiate between healthy, inflammatory, irradiated/​scarred brain tissue (e.g. within the context of radiation therapy or surgery planning) and especially for the early diagnosis of relapses.

Well-informed in all matters

Requirements for an FET PET-CT

  • Examination costs are not covered by statutory health insurers. Some private health insurers cover parts of the costs, and you should certainly submit our fee note to your private health insurer.
  • An individual tracer is produced for your examination depending on the medical condition.
  • If you are unable to keep the appointment, we would like to ask you to inform us at the latest by noon on the previous day; a cancellation fee will otherwise be charged.

Important information

  • Please bring any previous findings and images to your examination.
  • Please arrive at the examination nil by mouth. You should have had your last meal the night before the examination.
  • Drink plenty of water one hour before the examination.
  • A possible pregnancy must be ruled out.
  • Please inform us while making the appointment if you are a nursing mother so that we can discuss the further procedure with you.
  • Contact with pregnant women and toddlers should be avoided on the day of the examination.

Procedure for an FET PET-CT

  • We inject a small dose of radioactive tracer substance that has been specifically prepared for your examination.
  • The imaging process in the scanner takes 40 minutes and begins directly after the injection of the tracer.
  • You should drink plenty of liquids post-examination in order to accelerate the excretion of the tracer.
  • Please let us know if you suffer from claustrophobia.

Possible side effects

  • The injection of the radioactive tracer is not expected to cause any side effects.
  • However, side effects may result from the administration of the iodine-containing contrast agent within the context of a possible accompanying contrast agent-guided computer tomography (intolerance reaction, hyperthy­ro­idism, exacerbation of pre-existing renal insufficiency).
  • Please be sure to let us know within the context of the informed consent discussion if you have previously had a reaction to contrast agents (skin redness, itching, swelling, shortness of breath, etc.).

Waiting time for an appointment

Appointments with short waiting times are possible.

Costs & reimbursement

PET-CTs are currently not listed within the benefits catalogue of statutory health insurers and therefore only covered through private health insurance.
Our fee notes can be submitted in any case to all private health insurers that cover outpatient services.

Various tracers are used depending on the condition. We will gladly inform you about the costs during a personal consultation.

We ask you to, at the latest, cancel your appointment at noon on the day before the examination since tracers are specifically prepared for each examination.
A cancellation fee is charged in case of late appointment cancellation or if the examination cannot be performed.//
