Garantia de qualidade em medicina nuclear

Abstract

The main objective of the present dissertation was to execute and implement Quality Control (QC) protocols of the main equipment of the HPP-Molecular Medicine of Porto (HPP) and the Lenitudes- Medical Center & Research (LMCR) from the Lenitudes Group SGPS as an integrative part of the Quality Guarantee system. The QC nuclear medicine instrumentation is crucial due to its precise and reproducible performance that ensures an adequate operative system, the safety of patients and professional workers and guarantees the correct diagnostic and therapeutical procedures. Hence, routine QC tests of the existing equipment were carried out in both services, specifically dose calibrators, gamma cameras and PET/CT tests. In an initial phase, the accuracy, constancy, linearity and the geometry of the dose calibrators were evaluated. Next, QC tests of the gamma cameras were performed such as uniformity tests, center of rotation and the spatial resolution and linearity. Ultimately, the quality of the PET/TC image was analyzed. The obtained results were compared to the limits accepted by the current Portuguese legislation, with the manufacturers’ specifications and international guidelines. The detection of coherent values and the good operation of the equipment were observed from the analysis of the results. Furthermore, the application and execution of corrective measures were also deduced from the results analysis. From the QC execution and its analysis, QC protocols were developed and implemented in both services. The procedures are represented as future guidelines for QC analysis in the medical services.

A presente dissertação teve como principal objetivo a execução e implementação de protocolos de Controlo de Qualidade (CQ) dos principais aparelhos dos Serviços do HPPMedicina Molecular do Porto (HPP) e da Lenitudes-Medical Center & Research (LMCR) do Grupo Lenitudes SGPS como parte integrante do sistema de Garantia de Qualidade. O CQ da instrumentação de medicina nuclear é crucial ao seu desempenho preciso e reprodutível, garantindo o funcionamento adequado, bem como a segurança dos pacientes e trabalhadores e a garantia de procedimentos corretos de diagnóstico e terapêutica. Neste sentido, foram realizados testes de rotina de CQ aos equipamentos existentes em ambos os serviços, nomeadamente aos calibradores de dose, câmaras gama e PET/TC. Numa primeira fase, avaliou-se a exatidão, a constância, a linearidade e a geometria dos calibradores de dose. Seguidamente, realizaram-se os testes de CQ das câmaras gama: teste da uniformidade, centro de rotação e resolução e linearidade espaciais. Por fim, foi analisada a qualidade de imagem de PET/TC. Os resultados obtidos foram comparados aos limites de aceitação presentes na legislação portuguesa, com as especificações dos fabricantes dos equipamentos e guidelines internacionais. A sua análise permitiu observar a coerência dos valores e o bom funcionamento dos aparelhos, assim como solicitar e executar medidas corretivas. A partir da execução dos CQ e a sua análise, foram elaborados protocolos de CQ a serem implementados em ambos os serviços. Os procedimentos são apresentados como diretrizes para futuros CQ realizados nos serviços.
