Then, it focuses on kinetic modeling in PET. The purpose of kinetic modeling in PET is a description of radioactive tracer tissue uptake kinetics in mathematical terms. Assuming we have a mathematical model, an input function which provides the tracer concentration in blood as a function of time, and dynamic PET data which provide the tracer concentration in a tissue as a function of time, the kinetic parameters of a proposed model can be estimated. Kinetic parameters have relevant physiological interpretation, i.e provide the quantitative information about physiological processes that take place in an observed tissue or organ. Therefore, this article also introduces compartment models which are most often used method for describing the radioactive tracers tissue uptake, the concept of input function, and explaines the estimation of kinetic parameters</dc:description><dc:description xml:lang="sl">Članek najprej predstavi Pozitronsko Emisijsko Tomografijo (PET) kot funkcionalno in molekularno tehniko slikanja ter glavne fizikalne principe delovanja PET slikanja. Nato se osredotoči na kinetično modeliranje pri PET-u. Namen kinetičnega modeliranja pri PET-u je opis kinetike privzema radioaktivnega sledila v tkivih z matematičnimi termini. Če imamo na voljo matematičen model, vhodno funkcijo, ki vsebuje podatke o koncentraciji radioaktivnega sledila v krvi v odvisnosti od časa, in dinamične PET meritve, ki vsebujejo informacijo o koncentraciji radioaktivnega sledila v tkivu kot funkcijo časa, lahko ocenimo kinetične parametre predlaganega modela. Kinetični parametri nosijo relevantno fiziološko interpretacijo. Le ti zagotovijo kvantitativno informacijo o fizioloških procesih v določenem tkivu ali organu. Članek predstavi tudi razdelčne modele, ki se najpogosteje uporabljajo za opis privzema radioaktivnih sledil v tkivih, razloži koncept vhodne funkcije in pojasni ocenjevanje kinetičnih parametrov</dc:description><edm:type>TEXT</edm:type><dc:type xml:lang="sl">znanstveno časopisje</dc:type><dc:type xml:lang="en">journals</dc:type><dc:type rdf:resource="http://www.wikidata.org/entity/Q361785" /></edm:ProvidedCHO><ore:Aggregation rdf:about="http://www.dlib.si/?URN=URN:NBN:SI:doc-QX7YRYFJ"><edm:aggregatedCHO rdf:resource="URN:NBN:SI:doc-QX7YRYFJ" /><edm:isShownBy rdf:resource="http://www.dlib.si/stream/URN:NBN:SI:doc-QX7YRYFJ/ad45-a4896a0f1-2-e7deb5bb2c34-0abaa7/PDF" /><edm:rights rdf:resource="http://rightsstatements.org/vocab/InC/1.0/" /><edm:provider>Slovenian National E-content Aggregator</edm:provider><edm:dataProvider xml:lang="en">National and University Library of Slovenia</edm:dataProvider><edm:object rdf:resource="http://www.dlib.si/streamdb/URN:NBN:SI:doc-QX7YRYFJ/maxi/edm" /><edm:isShownAt rdf:resource="http://www.dlib.si/details/URN:NBN:SI:doc-QX7YRYFJ" /></ore:Aggregation></rdf:RDF>
