SRTM2 was used as reference method. Data are expressed as mean ± SD. Slope, y-axis intercept, and r2 are parameters of linear regression analyses with SRTM2 as reference method (x-axis). Linear regressions were calculated across all regions (i.e., 14 patients × 2 volumes of interest × 2 hemispheres = 56 data points).
