Information about PET/CT for Patients

A PET/CT scan is a method of nuclear medicine diagnostic imaging. This method is used primarily for diagnosing cancer or inflammation that utilises fusion: a combination of functional (metabolic) and anatomical (morphological) images.

The Department of Nuclear Medicine performs the following examinations:

• PET/CT of the trunk using the radiopharmaceutical fluorodeoxyglucose (FDG),
• PET/CT of the trunk using the radiopharmaceutical fluorocholine (FCh),
• PET/CT of the trunk using the radiopharmaceutical 18F-fluciclovine (Axumin),
• PET/CT of the brain using the radiopharmaceutical fluorodeoxyglucose (FDG),
• PET/CT of the brain using the radiopharmaceutical 18F-fluoromisonidazole (F-MISO)
• PET/CT for radiotherapy planning.

Appointment scheduling periods are short, ranging from 3 to 4 weeks. We will be happy to call you if an earlier appointment becomes available.

PET/CT scanning is among the most advanced imaging methods. It combines the advantages of a metabolic examination (PET) and structural imaging (CT). This is also called hybrid imaging. This makes it possible to determine the exact anatomical localisation of the pathological finding while also clarifying structural changes. It significantly improves the usefulness of both of the methods. Carrying out both examinations at the same time simplifies an often lengthy, demanding process for patients.

• The most frequently used method in oncology – for patients with suspected or confirmed cancer. For these cases, PET/CT scans are performed prior to the commencement of their treatment (the treatment process is changed in 25% of cases based on this examination). The examination is also often performed as a post-treatment check-up (an assessment of the efficacy of a treatment and possible modification thereof) or to plan radiotherapy.
• PET(CT is also used in diagnostics for inflammatory or autoimmune diseases, neurology, and cardiology.

The use of radiopharmaceuticals

To produce a metabolic image, it is necessary to administer intravenously special radioactive substances, called radiopharmaceuticals (most often F-fluorodeoxyglucose (FDG) and F-choline (FCH)). The administered radioactive substances are rapidly excreted from the patient’s body via urine, do not cause allergic reactions, and do not require restrictions on driving motor vehicles. However, if you have been given other medications, please consult your capacity to drive motor vehicles with your doctor.

The morphological image is obtained using a full CT scan with the application of an iodine contrast (unless contraindicated). The examination is time-consuming, it takes approximately 3 hours because it is typically used to scan large areas of the body (it is called a whole-body scan).

How to schedule an appointment for a PET/CT scan

To schedule an appointment for a PET/CT scan, i.e. a positron emission tomography-computed tomography scan, please call +420 222 999 046 to reserve a time slot. Then send the completed request to the following e-mail address: zadanky@ptc.cz. This makes the scheduling system easier and faster.

2. What do you need for your PET/CT scanning?

• A request form issued by your attending physician (general practitioner or specialist physician – oncologist, pulmonologist, rheumatologist, surgeon, haematologist, neurologist, cardiologist… etc.).
• A valid insurance card.
• ID card.

· Patient information for a PET/CT scan

Based on clinical findings, your doctor has recommended PET/CT scanning. We have prepared basic information to save you any worry about the examination. You will learn what the examination is, what will happen during the examination, how long the examination takes and whether there are any restrictions.

· Patient’s informed consent for PET/CT scanning

You can read the informed consent for PET/CT scanning in the comfort of your own home. You will fill it out and sign it when you arrive at the Proton Center.
