This document proposes reference levels for radiation doses in the diagnosis of coronary artery disease using CTA. The diagnostic reference levels (DRLs) refer to the radiation doses a patient receives during a specific examination procedure under routine conditions. DRLs are not a reference for the radiation doses an individual receives during a CT examination, but rather a reference level for radiation doses in a specific region or nationwide, derived from large-scale surveys. This document applies to the radiation safety and quality control of coronary artery CT examinations. This document is a general reference document. Where appropriate, the scanning radiation dose standards should be further refined based on the patient's age, body type, indications, scanning equipment, etc., in order to reduce radiation doses as much as possible while meeting the requirements for CT diagnosis.
