Fig. 3
Distribution of ASP values with the reference algorithm. ASP values at reconstructed spatial resolution of 7.0-mm FWHM and acquisition time of 180 s are displayed for each of the 50 patients for TOF4/8/6, PSF + TOF2/17/7 and Q.Clear1750. The cutoff at 19.5% is highlighted at each axis. Several tumors feature ASP in proximity to this cutoff. Data points that are located either in the left upper section or in the right lower section of the diagram represent discordantly classified cases when compared to the reference algorithm TOF4/16/6.4 (TOF4/8/6, n = 1; PSF + TOF2/17/7, n = 2; Q.Clear1750, n = 5 discordant cases)
