Lesion detection in the standard and RPP groups
liver lesions
In the arterial phase, we observed a significant difference in lesion detection rates between the standard group and the RPP group with 50-keV reconstruction (FOM: 0.594 vs. 0.825, respectively; p = 0.006) (Table 
Comparison of lesion detection rates between the standard and RPP groupsNote: CI = confidence interval, FLLs = focal liver lesions, RPP = renal protection protocol. Figure of merit was not calculated for FLLs ≥ 20 mm due to the small number of FLLs (n = 12).
