Table 2 Intra- and Inter-observer agreements among the semi-quantitative measurements on PET/CT, expressed as intraclass correlation coefficients

From: Volumetric parameters on 18F-FDG PET/CT predict the survival of patients with gastric cancer associated with their expression status of c-MET

SUVmax 0.907 (0.859–0.933) 0.901 (0.810–0.914)
SUVpeak 0.890 (0.837–0.922) 0.884 (0.834–0.910)
MTV 0.831 (0.747–0.894) 0.841 (0.732–0.896)
TLG 0.818 (0.733–0.887) 0.809 (0.728–0.857)
