Scope

Scope: This document proposes diagnostic reference levels (DRLs) for radiation doses in clinical diagnosis of multi-slice spiral CT. DRLs are not a reference for individual radiation doses during CT examinations, but rather a reference level for radiation doses in a specific region or nationwide, obtained after a large-scale survey. This document applies to radiation safety and quality control in multi-slice spiral CT examinations. This document is a general reference document. Where appropriate, scan radiation dose standards should be further refined based on patient age, body type, indications, scanning equipment, etc., to minimize radiation doses while meeting CT diagnostic requirements. This document is a general requirement. For specific parts of the body, if there are professional standards, those standards should be followed. Note: The data for CT diagnostic radiation dose reference levels provided in this document come from five comprehensive hospitals in China, and data from grassroots hospitals were not included. Considering the significant differences in radiation doses for children at different ages, future studies will further break down the data by age to provide radiation dose reference levels for children of different ages. Main technical content: This document proposes diagnostic reference levels (DRLs) for radiation doses in clinical diagnosis of multi-slice spiral CT.
