Evolução da legislação do controle de qualidade de equipamento de tomografia computadorizada no Brasil

Abstract

Computerized tomography is a imaging diagnostic examination that has several applications, used mainly in the medical and dental fields. In order to enable examinations with better quality and with greater radiological safety in 1998 was published the first regulation the Ordinance No. 453, of 1 June 1998. Due to the constant technological development, changes have occurred in the performance of the equipment and in the quality control procedures, thus, the 1998 Order was repealed by Resolution No. 330, of December 20, 2019, which in 2022 was revoked by resolution No. 611, of March 9, 2022, which remains in force. With the aim of evaluating the evolution of quality control legislation in Brazil, we compared the main standards and standards versed over the years on quality control, to analyze whether there has been improvement in the criteria of acceptance tests, whether new quality control proposals have succeeded and to assess whether the new legislation provides higher quality of diagnosis and radiological safety. For this review, the legislation and regulations in Brazil issued by bodies at the federal level, such as the National Nuclear Energy Commission and the National Health Surveillance Agency, were used. In addition to scientific articles published in national and international journals by Brazilian researchers. In order to analyze these data, a comparison device has been created for the quality control tests of acceptance, usability, responsibility and incorporation of new technologies. From this comparison device it was noted that between the portaries and resolutions there was the withdrawal of two quality control tests, as well as the creation of nine new tests. In addition, there has been a change in the level of tolerance and periodicity between the long tests of the new legislation. It is concluded that these changes were necessary to improve the quality and safety of radiology services.
