Mri con contraste software#By using a quantication tool, the potential of our software is shown. The simulated images can be then processed using different quantication tools, enabling the user to compare their performance and sensitivity. In this work, a software tool that allows the user to set some acquisition parameters was depeloped, and by using known parametric maps, DCE-MRI acquisitions were simulated. Developing a tool that allows the user to guarantee the accuracy of quantication tools and to study their robustness and sensibility is the purpose of this thesis. Inconsistencies due magnetic field inhomogeneities, patient movement, errors induced by the limited temporal and spatial resolution of the scanner, non-locality of the arterial input function and noise, among others, lead to estimated parameters with signicant uncertainties. ![]() Quantitative imaging, based on dynamic contrast-enhanced magnetic resonance, is an estimation process that involves several variables. Finalmente, haciendo uso de un algoritmo de cuantificación, seĮxpone el potencial del software al realizar un breve estudio de incertidumbres y sensibilidad, culminando con un estudio sobre la optimización de los tiempos de adquisición y niveles de ruido en la clínica. ![]() De esta manera, permite comparar el desempeño y sensibilidad de dichas herramientas. Desarrollar una herramienta que permita validar algoritmos de cuantificación y estudiar sus grados de incertidumbre asociados es el propósito de esta tesis.Įn este trabajo se desarrollo un programa que permite controlar a voluntad diferentes parámetros de adquisición y, a partir de mapas paramétricos conocidos, simular adquisiciones DCE-MRI para ser procesadas por diferentes algoritmos de cuantificación. Inconsistencias debidas a la inhomogeneidad del campo, movimientos del paciente, as como errores introducidos por la resolución temporal y espacial, la no localidad de la función arterial deĮntrada, ruido, entre varios otros, llevan a una estimación de parámetros con una incertidumbre asociada importante. La cuantificación de parámetros asociados a la perfusión sanguínea a través de imágenes dinámicas de resonancia magnética con contraste (DCE-MRI) es un proceso indirecto que involucra numerosas variables. ![]()
