Fig. 3From: Comparative evaluation of SUV, tumor-to-blood standard uptake ratio (SUR), and dual time point measurements for assessment of the metabolic uptake rate in FDG PETThe fractional difference δSUR between the first and second time points of each DTP measurement. δSUR of the actual values (the fractional difference between measured SUR2 and SUR1 of the DTP pairs) is shown in red. δSUR after scan time correction of SUR2 from T 2 to T 1 is depicted in blue Back to article page
