Modern Diagnostic Examinations

Part of the Proton Therapy Center is also the Department of Radiodiagnostics and Nuclear Medicine. In addition to treatment, patients can undergo diagnostic examinations such as Magnetic Resonance Imaging (MRI) and Positron Emission Tomography in combination with Computed Tomography (PET/CT).

Magnetic Resonance Imaging (MRI)

Magnetic Resonance Imaging (MRI)

We perform the following examinations:

  • MRI of the head (for example brain including MRI angiography, brain spectroscopy);
  • MRI of the limbs, joints, spine (cervical, thoracic, or lumbar);
  • MRI of soft tissues;
  • MRI imaging of the neck, chest, abdomen, pelvis;
  • MRI angiography;
  • MRI spectroscopy;
  • MRI biliary and pancreatic ducts without endoscopic intervention (cholangiopancreaticography);
  • MRI of the breast.

 

The wait time is typically short, ranging from 2 to 4 weeks. We will be happy to help you arrange the date most suitable to your needs.

How To Schedule Your MRI

Please send your doctor's referral for the examination to zadanky@ptc.cz. We will contact you as soon as possible. If you wish to be called, rather than emailed, you can also include your phone number in your message.

If you cannot send your doctor's referral via e-mail, please contact the reception of the Radiodiagnostics Department at +420 222 999 070, and they will advise you on how to proceed.

For some types of MRI examinations, the administration of a contrast agent is typically necessary. Therefore, we require prior laboratory control of your renal function (creatinine, urea). Alternatively, it is possible to perform only a native, less extensive, examination. We can arrange this blood work at our facility. However, please let us know in advance so that we can arrange your appointments accordingly.

 

MRI Restrictions

The MRI examination cannot be done in patients with:

  • implanted pacemaker or defibrillator;
  • cochlear implant.

If you have any electronic or metal implant, or another foreign body, it does not automatically mean that you cannot undergo the MRI. However, you must always report such fact to the reception staff and subsequently to the MRI operator before scheduling your examination. They will make a qualified decision on whether or not you can undergo the examination safely.

 

MRI Of The Breast

Breast MRI is increasingly being used to better visualize focal breast lesions. The MRI examinations should be performed primarily in women with an increased risk of breast cancer. These are women whose mother or grandmother had breast cancer, have a genetic predisposition, are 30 or more years after irradiation of the chest or mediastinum, or are being monitored for benign breast cancer.

Breast MRI allows better detection of the extent of the tumor before surgery or irradiation. Examinations may also be performed on women who have breast implants and for whom ultrasound has not provided sufficient information, as well as women after cosmetic procedures.

In the case of oncological disease, breast MRI can provide information on the response to radiation or chemotherapy, or it is used for further monitoring and control after the disease. The examination can also be performed in patients with enlarged nodules in the armpit (axillae), where the primary source is not known, or in patients with suspected tumor on a previous mammographic examination. The dynamic sequences that are acquired during the MRI help to differentiate between malignant and non-malignant lesions according to the type of saturation of these lesions, therefore the MRI examination in the diagnosis of breast cancer is very beneficial and has a significant yield.

PET/CT

PET/CT

We perform the following examinations:

  • PET/CT using the radiopharmaceutical fluorodeoxyglucose (FDG), administered intravenously;
  • PET/CT using the radiopharmaceutical fluorocholine (FCh);
  • PET/CT using radiopharmaceutical 18F-fluciclovin (Axumin);
  • PET/CT of the brain using the radiopharmaceutical fluorodeoxyglucose (FDG);
  • PET/CT for radiotherapy planning.

 

The wait time is typically short, ranging from 2 to 3 weeks. We will be happy to help you arrange the date most suitable to your needs.

The PET/CT is a non-invasive diagnostic imaging method. It combines the benefits of the PET (positron emission tomography) and the CT (computed tomography) in one examination. A prerequisite is the administration of a radioactive substance (for the PET) and the possible administration of iodinated contrast agent (for the display of morphological CT). Thanks to this, it makes it possible to determine the exact anatomical location of the pathological finding and, at the same time, to clarify unclear structural changes. This significantly increases the yield of both methods. The simultaneous performance of both examinations simplifies the otherwise often lengthy, patient-demanding examination process.

  • This method is most often used in oncology, in patients with suspected cancer or with already confirmed cancer. In this case, the examination is performed before the start of treatment (based on this examination, the treatment procedure is changed in up to 25% of cases).
  • However, the examination is also often performed as a control after the performed treatment (evaluation of the effect of the treatment and for its possible adjustment) or for the planning of radiotherapy.
  • The PET/CT is also used in the diagnosis of inflammatory, autoimmune diseases, in neurology, and cardiology.

 

Radiopharmaceuticals

Intravenous administration of special radioactive substances, called radiopharmaceuticals (most commonly F-fluorodeoxyglucose (FDG) and F-choline (FCH), is required to produce a metabolic picture. If you have been given other medicines, please consult with your doctor if you can drive.

We obtain the morphological picture with the help of a full-fledged CT examination, with the application of iodine contrast (if it is not contraindicated). The examination is time consuming, it takes about 3 hours, because a large body is scanned as standard (called a whole-body examination).

 

How To Schedule Your PET/CT

Please send your doctor's referral for the examination to zadanky@ptc.cz. We will contact you as soon as possible. If you wish to be called, rather than emailed, you can also include your phone number in your message.

If you cannot send your doctor's referral via e-mail, please contact the reception of the Radiodiagnostics Department at +420 222 999 046, and they will advise you on how to proceed.
