Resumen
Mediante la participación de Costa Rica en el proyecto del OIEA/CRP E1.30.39: Mejora de la capacidad
para la detección temprana y el diagnóstico del cáncer de mama a través de imágenes, como uno de sus objetivos; se
inician en el país los primeros esfuerzos para desarrollar pruebas de control de calidad de manera remota en equipos de
mamografía digital. Bajo este contexto, el objetivo de este trabajo fue implementar en el Servicio de Radiología del Hospital
Max Peralta de San José de Costa Rica una plataforma para desarrollar pruebas de control de calidad de manera remota,
con el fin de monitorear el desempeño del equipo de mamografía digital y así, poder tomar las acciones correctivas para
asegurar la calidad de la imagen evitando perjudicar el diagnóstico y la sobre exposición del paciente. Para ello, se desarrolló inicialmente una plataforma que permitía el envío de los datos de control de calidad por medio de teléfonos inteligentes.
Posteriormente, por medio de una página web (tiempo real) a la cual tienen acceso las tecnólogas del Servicio de Radiología del Hospital Max Peralta, se enviaban los datos semanalmente que evaluaban parámetros relativos a la calidad de
imagen del mamógrafo Siemens Inspiration. Los anterior permitió reunir un registro de datos de monitoreo de más de 4
años para las variables, relación señal ruido (SNR) y relación diferencia de señal ruido (SDNR), donde se observó el
comportamiento y se generaron avisos de alerta al superar de la tolerancia esperada. Esta información permitió la toma
oportuna de decisiones para garantizar la calidad final de la imagen. La presencia en los centros médicos de físicos médicos calificados en el área de radiología con énfasis en mamografía es muy escasa en la mayoría de las regiones del mundo.
Por lo tanto, el desarrollo de plataformas que permitan el envío de resultados de pruebas de control de calidad de manera
remota para su evaluación complementa los programas formales que deben desarrollarse en la institución.
Through Costa Rica participation in the project of OIEA/CRP E1.30.39: Capacity Improvement for breast cancer early detection and diagnosis using images; as one of its objectives, the first efforts for developing remotely quality control tests in digital mammography equipment are initiated in the country. In this context, the aim of this work was to implement a platform in the Radiology Department of Max Peralta Hospital to develop remotely quality control tests, in order to monitor the performance of the digital mammography equipment, so corrective actions can be done to ensure image quality avoiding harming the diagnosis and patient overexposure. For that reason, a platform was initially developed for the sent of quality control data via smartphones. Subsequently, through a web page (real time), which technologists from the Radiology Department of Max Peralta Hospital have access, the assessment data of relative parameters to the image quality of the Siemens Inspiration mammography device was sent weekly. This allowed creating a monitoring data register of more than 4 years for variables such as the Signal-to-noise ratio (SNR) and the Signal-difference-to-noise ratio (SDNR), where the behavior was observed and warnings were generated when leaving the expected tolerance. This information allowed taking an appropriate decision to ensure the final image quality. In medical centers. In medical centers, the presence of medical physicists qualified in the radiology area with emphasis on mammography it´s very scarce. Therefore, the development of platforms that allow the remotely sending of quality control tests for its assessment complements the formal programs that should be developed in the institution.
