Auxílio à detecção de anormalidade perfusional miocárdica utilizando atlas de SPECT e registro de imagens: resultados preliminares

Abstract: OBJETIVO: Criar um atlas de cintilografia de perfusão miocárdica e verificar sua aplicabilidade no auxílio computadorizado à detecção de defeitos perfusionais miocárdicos em pacientes portadores de cardiopatia isquêmica. MATERIAIS E MÉTODOS: O atlas foi criado com imagens de cintilografia de perfusão miocárdica, em condições de repouso e estresse, de 20 pacientes de ambos os gêneros com baixa probabilidade de doença arterial coronariana e julgadas normais por dois observadores experientes. Técnicas de registro… Show more

“…Computer-aided diagnosis (CAD) can be defined as a diagnosis made by a radiologist who utilizes the result from automated quantitative analyses of radiographic images as a second opinion in the diagnostic decision making process (12) . The purpose of CAD is to improve accuracy in diagnosis, as well as the consistency of radiological images interpretation, by utilizing the output from the computer as a reference (13)(14)(15) . Today, the standard for the utilization of CAD systems is still based on the model of a standalone workstation, without the integration of the obtained results with the information system or with the PACS.…”
