Table 2 Number of compartments that SAIF approach returned to describe the kinetics of 18F-FDG. Average and standard deviation among patients of the percentages of voxels resulting from SAIF in one, two or three reversible compartments (plus trapping) are reported

From: The kinetics of 18F-FDG in lung cancer: compartmental models and voxel analysis
