Fig. 6From: O-(2-[18F]fluoroethyl)-l-tyrosine PET in gliomas: influence of data processing in different centresCorrelation of slope of the TAC of 18F-FET uptake from 10 to 40 min p.i. There is a significant correlation but a deviation from line of unity indicating lower slope values for centre A. High-grade tumours are indicated by red symbols and low-grade tumour by green symbolsBack to article page
