Elaboração de procedimento operacional padrão dos testes de qualidade diários do ativímetro CRC-55tR

Abstract

The activity meter or activitymeter, as it is also called in the literature, is an important instrument used in nuclear medicine to correctly measure the amount of activity contained in the radiopharmaceutical that will be applied to the patient, whether in PETCT procedures or conventional scintigraphy. In nuclear medicine, unlike other areas of conventional radiology, drugs containing a radioactive isotope, called radiopharmaceuticals, are administered to the patient who will undergo the diagnostic procedure or therapeutic applications. For this process to occur safely for both the patient and the radiology professional who will be in charge of the exam, it is very important that the measurement of the dose of radiopharmaceutical prescribed for this patient is carried out correctly, and this is done using the equipment activitymeter. The present work sought, through observation of the routine of a nuclear medicine professional and studies in articles, books and standards, to understand and formalize a document that helps the radiology technologist to carry out daily quality tests of the activity meter, precisely the CRC model. -55rT, só that it can reliably carry out measurements on radiopharmaceuticals that will be injected into patients. To produce this document, which is classified as a “Standard Operating Procedure”, in addition to the materials already mentioned, the CRC-55rT activity meter manual was studied, which is crucial to understanding how to use the equipment’s functions. Using the equipment made available by the DAPI clinic, Mercês headquarters, it was possible to carry out in practice the entire daily routine of activity meter quality control tests and record each step in this document, leaving it available for any radiology technologist to read. It and learn how to perform the tests.
