PET centre – ambulatory health-care facility in the field of nuclear medicine exerts diagnostic examinations using traditional as well as positron radiopharmaceuticals. Major instrumentation of the facility consists of PET/CT tomograph GE Discovery LS and coincidence SPECT/CT gamma-camera GE MilleniumVG Hawkeye. Both apparatuses allow to combine functional and metabolic image scanning along with CT examination within one examination. This unique hybrid mode of imaging expressly leads to précising and to enhancement of examinations, and PET/CT tomograph is currently the first apparatus of this type in SR. Utilization of both apparatuses is particularly useful in diagnostics of oncologic, cardiovascular and neurologic diseases. PET centre is prepared to ensure ten to fifteen PET/CT diagnostic examination per day and to exert whole spectrum of nuclear medicine examinations.
