简要总结
The study is a cross sectional observational study and will be done in two phase.
Phase 1: Include 143 patients.Scanning will be performed using standard pediatric brain protocol. Dose info such as CTDI vol and DLP will be noted at the end of the scan and effective dose will be calculated from DLP. The 3rd quartile value of CTDI vol and DLP will be calculated to establish Diagnostic Reference Levels.
Phase2: Scanning will be performed using low dose pediatric brain protocol. Dose info such as CTDI vol and DLP will be noted at the end of the scan and effective dose will be calculated from DLP. Subjective and objective assessment of image quality will be done. The 3rd quartile value of CTDI vol and DLP will be calculated to establish Diagnostic Reference Levels for low dose.
