Table 2.
Clinical image quality scoring from three readers of 50 test whole-body scans based on different criteria, mean ± standard deviation. 0 is non-diagnostic; 5 is excellent. Bold indicates the best (highest) score for each metric. The intraclass correlation coefficient (ICC) is also provided for each metric (95% confidence interval) to show reader agreement. P-values (in parentheses) are given with respect to ToF BSREM (with p-values with respect to non-ToF BSREM shown in Suppl. Table 5)

| Non-ToF BSREM | 3.03 ± 0.40 (< 0.001) | 3.03 ± 0.43 (< 0.001) | 3.36 ± 0.40 (1.000) |

| DL-ToF(H) | 3.83 ± 0.38 (0.11) | 4.18 ± 0.39 (1.000) | 3.39 ± 0.40 (0.96) |
