Box-and-whisker plot comparing the Akaike weights (A) and percentage of
voxels (B) with the lowest Akaike information Criterion AICc within the region
of interest (ROI) for the two-compartment exchange model (2CXM), compartmental
tissue uptake model (CTUM), extended Tofts model (ETM), and Tofts model (TM),
from 18 papillary thyroid cancer patients. Each box plot shows minimum, first
quartile, median (black line), third quartile, and maximum values. ETM estimated
percentage of voxels with the lowest AICc were significantly different from
2CXM, CTUM, and TM (ANOVA, P<0.0001).
