Bland-Altman plots and intra-class correlation coefficients (ICC). With 95% confidence intervals in the parentheses of defect size measurement reproducibility between no and light (1.5-mm kernel size) or heavy (2.5-mm kernel size) filtering for the high-sensitivity (HS) pinhole collimator. The results for low (25 MBq) injection dose are shown in upper panels; those for high (200 MBq) injection dose in lower panels. Solid lines indicate mean difference; dotted lines, 95% limits of agreement; G1.5 mm, Gaussian filter of 1.5-mm kernel size; G2.5 mm, Gaussian filter of 2.5-mm kernel size.
