Analysis of the Advances of RDC 330/19 in relation to Ordinance 453/98 under the Radiation Protection Focus

Almost twenty years after the publication of Ordinance 453, the National Health Surveillance Agency (ANVISA) approved the Collegiate Board Resolution 330 (RDC 330), which establishes the basic guidelines for Radiation Protection (RP) in diagnostic and interventional radiology and regulates the use of X-ray diagnostic methods throughout the national territory. Therefore, when observing the radiodiagnostic service and its changes suffered in recent decades, the addition of new modalities is noticeable, as well as changes in the service flow, brought about as a result of the advancement of new technologies. The RDC 330 came with several changes even in its format: a document with the basic guidelines for radioprotection and several Normative Instructions (INs) - one for each technology in diagnostic imaging. Among the INs, IN58 and IN59 can be mentioned, which provide for sanitary requirements for quality assurance and safety in ultrasound and magnetic resonance systems, respectively, which now makes quality control mandatory. The RDC 330 and its respective IN were developed to meet all these needs, contextualizing the principles already established for the elevation of the RP culture and diagnostic quality. Therefore, the implementation of RDC 330 is defended, in view of the need for agile adaptation that can ensure improvements in the quality of imaging services, dose optimization and in the quality control of radiodiagnostic equipment, promoting the safety of patients, population and workers exposed to ionizing radiation.
