Application of AIIR algorithm for quality improvement and noise reduction in pediatric abdominal contrast-enhanced CT.

DeLong's test revealed no statistically significant difference between the two scores ( P = 0.365), indicating that although AIIR exhibited numerically higher diagnostic efficacy in this study sample, it did not reach statistical significance. 3.5 Radiation dose and contrast agent administration The radiation dose parameters in the arterial phase CT scan of the experimental group were significantly lower than those in the conventional group (all P values <0.05), with CTDIvol, DLP, and ED reduced by 22.36%,21.05%, and 23.61%, respectively.
