Nuclear medicine is a medical specialty which purpose is to diagnose and treatment by using
radioisotopes in the form of non-sealed radioactive sources. Those radionuclides and/or
radiopharmaceuticals, radiation emitters, are administered to the patient making them a
temporary source. The Gamma Camera is a device used to detect radiation emitted by the
patient, so the radiation is converted into electrical signals, generating, at the end of the
process, an image. Therefore, quality control of Gamma Camera is a vital component evaluating
the quality of the equipment to produce scintigraphic images, because during the processes in
order to acquire those images are measured possible failures that can directly affect their
integrity. Intending that importance, the goal of this paper is to perform the quality control settled
by International Atomic Energy Agency (IAEA), National Equipment Manufacturers Association
(NEMA) and Comissão Nacional de Energia Nuclear (CNEN), the national normative and
supervisory institution of Brazil, on an equipment SPECT (Single Photon Emission Computed
Tomography) type in a Brazilian Nuclear Medicine service. The tests were performed, recorded
and evaluated to ensure they are within the standards required by the named agencies. The
results indicate the obtained values are within the parameters established by the IAEA, NEMA
and CNEN. By that, it’s evidenced the equipment has its complexity and it’s extremely important
in a Medicine Nuclear service, being necessary an efficient program of quality control in order to
ensure the proper functioning of the equipment and avoid erroneous diagnosis.
