Table 2 Results of total kidney values: mean values ± standard deviation (SD) as well as total errors, correlation coefficient (r), differences from Bland-Altman analysis (BA), and the p values from the Student’s t test. Displayed parameters are outflow efficiency (OE), mean transit time (MTT), and split function (SF); the latter for the integral 1 to 2 min in case of FDG values, and 1 to 3 min in the case of reference values
