Radioisotope scanning and positron emission tomography (PET/CT)


Radioisotope scanning is a modern imaging technique based on the use of radionuclide-labeled chemical compounds. It is used in almost every area of medicine. This method differs from other diagnostic imaging services such as ultrasound, X-ray, CT and MRI in that it is able to assess the functional state of organs and tissues, cell metabolism and receptor status.

The service is provided by our dedicated team of highly qualified radiologists of the Radioisotope Scanning Unit and Nuclear Medicine Laboratory. The Nuclear Medicine Laboratory provides scientific guidance and diagnostic quality assurance.

Two major diagnostic modalities are:

  • Radioisotope testing — laboratory testing of thyroid hormones, adrenal glands, sex hormones, etc., the concentration of biologically active substances and tumor markers, including PSA and CA 125
  • Radioisotope imaging— detection of internal diseases by scintigraphy and combined positron emission tomography/computed tomography (PET/CT). Indications for radioisotope scanning are determined by your doctor depending on the disease and the expected result.


Due to the short half-life of radionuclides used for PET the radiation load for patients is lower or comparable to that in X-ray.

Pregnancy is a relative contraindication to radioisotope scans.
