Abstract
18F-FDG PET/CT is the most widely used diagnostic modality for detection of malignant disease. Beside the visual insight of FDG pathways into the human body, PET/CT can give valuable information based on the SUV values. The SUV is a quantitative parameter of metabolic activity. FDG application has 2 major impacts on PET/CT: qualitative aspect (visual insight of FDG in the body) and quantitative aspect (degradation of the SUV values). Based on the literature, FDG extravasation incidence is 31% for all PET/CT studies and in 8% of all cases extravasation has been visually confirmed since the application place has been in the field of view. By constantly developing the technique, work methodology and increasing the quality control of the staff in the PET/CT department, the incidence of extravasation can be significantly reduced based on the results from the literature. In the case when paravenous injection is present on PET/CT images we can use certain software procedures to improve image quality and SUV quanitification.

Summary
Nekoliko je metoda koje nauÿnici istiÿu, a najjednostavnija metoda izraÿuna ekstravazata je manuealno iscrtavanje regije interesa Ovaj sistem rada inžinjeru medicinske Injection Quality for 18F-FDG, 68Ga-PSMA radiologije može ukazati na pojavu ekstravazacije and 68Ga-DOTATATE Positron Emission prije same PET/CT akvizicije, te može biti od Tomography" istiÿe se moguýnost prevencije ili velikog znaÿaja za unapreĀenje rada osoblja na ÿak korekcije paravenske aplikacije i drugih PET. Muzaffar i saradnici su u studiji "Novel method to detect and characterize 18F-FDG infiltration at the injection site: A single-institution experience" dodatno unaprijedili upotrebu TAC senzora kod ekstravazacije sa nalazima koje su DOTATATE i drugi. Pored znaÿaja TAC senzora nauÿnici istiÿu da automatski injektori, mobilni ili stacionarni znaÿajno smanjuju incidencu paravenoznih aplikacija u poreĀenju sa ruÿnim naÿinom aplikacije (14). Nakon analize da ÿak 63% sluÿajeva ekstravazacija nije uopšte stanja uvedena je u sistem nadzora aplikacije vidljivo na PET/CT snimcima.
