Brain imaging is the most common form of CT scan for kids, which shows how important it is to have protocols that use low radiation doses to lower the chance of harm. This is important since kids are more sensitive to radiation than adults. The study aimed to compare parameter CT low-dose protocol and parameter a standard-dose protocol. The objective of this study was to perform a comparative analysis of parameter values between pediatric head CT protocols utilizing low-dose and standard-dose techniques.This was cross-sectional study. A total of 100 CT scans of the head, Albatol teaching Hospital In the diyala governorate. SPSS software version 2019 was used to analyze the results. The results showed a significant difference in both radiation dose and examination time between the standard and low-dose protocols (p > 0.05), with a lower radiation dose recorded in the low-dose protocol group, while no statistically significant differences were recorded in examination length between the two groups (p = 0.7342). The low-dose CT protocol significantly reduced radiation exposure in pediatric patients by lowering CTDIvol, DLP, and effective dose, while also decreasing tube current and scan time. Scan length showed no significant influence on dose reduction.
