| Abstract: | PET/CT using 18F-fluorodeoxyglucose (FDG-PET/CT) is performed at the Institute of Oncology Ljubljana. PET/CT combines Positron Emission Tomography, which shows metabolism and function of the cells, with Computed Tomography, which shows detailed anatomy. FDG –PET/CT plays a major part in diagnostic evaluation of patients with suspected malignant tumors, in staging of malignancies and in therapy monitoring. Correct preparation of patients for the PET is important to ensure maximum diagnostic yield. The most important steps to be taken are control of glucose level, minimizing effects of physiological activity, and timing of scan performance. Due to a number of causes yielding false negative or false positive results, several interpretation criteria should be used to evaluate images. |
