[Imaging characterization of renal masses. Image atlas]. / Caracterización por la imagen de las masas renales. Atlas por la imagen.

The diagnostic study, analysis and characterization of renal masses and their behavior is one of the key elements for elaborating a surgical or therapeutic strategy, determining the prognosis, and for the follow-up of treatment efficacy in patients with benign or malignant disease. At present, computed tomography (CT) and magnetic resonance imaging (MRI) are the two most reliable, effective and efficient instruments in this context--offering sensitivity and specificity values in excess of 87%, with a diagnostic relaibility of over 90% in application to renal masses of a cystic or complex nature, with nonspecific or specific inflammatory characteristics, or of a primary or secondary neoplastic nature. The aim of this study is to present the principal CT and MRI parameters in relation to renal pathology of this kind, correlating them to the clinical, physiopathological and histopathological data with a view to affording architectural, density, signal intensity and biological behavior parametric information of help in understanding the changes occurring in the renal and retroperitoneal regions secondary to such pathologies.

El estudio diagnóstico, análisis y caracterización de las masas renales y su comportamiento representa uno de los pilares maestros para la elaboración de una estrategia quirúrgica o terapeútica de otros órdenes, en la elaboración de un pronóstico y en el seguimiento de la eficacia terapeútica tanto en casos de patología benigna como maligna. La TC y la RMI representan, en la actualidad, los dos modos más fiables, eficaces y eficientes en tal tipo de análisis y caracterización con índices de sensibilidad y especificidad superiores el 87% y con una fiabilidad diagnóstica superior al 90% dentro de las masas renales, sean quísticas simples o complejas, de orden inflamatorio inespecífico o específico o de origen tumoral primario o secundario de la esfera renal. El propósito de este estudio es el demostrar los principales parámetros de estudio mediante TC y RMI de tales tipos patológicos y correlacionarlos con los datos clínicos, patofisiológicos e histopatológicos para obtener datos paramétricos en arquitectura, densidad, intensidad de señal y comportamiento biológico que nos ayuden a comprender los cambios que se producen en el área renal y retroperitoneal derivados de tales patologías (AU)
