Values of the apparent diffusion coefficient in the differential diagnosis of tumors of the posterior fossa in the pediatric population of Colombia

Abstract: Introducción. Los tumores de la fosa posterior son frecuentes en la población pediátrica y requieren de una adecuada caracterización mediante resonancia magnética (RM) estructural y técnicas avanzadas de RM para lograr un enfoque terapéutico apropiado. Objetivo. Determinar la utilidad de los valores del coeficiente de difusión aparente (ADC cuantitativo) en el diagnóstico diferencial de los tumores de la fosa posterior en población pediátrica de un hospital de referencia en Bogotá D.C., Colombia. Materiales y … Show more

“…Previous non-radiomics studies reported a lower SEN and SPE when distinguishing between pediatric posterior fossa tumors. For instance, one study achieved an SEN of 81.82% and an SPE of 76.47% for MB, and an SEN of 66.67% and SPE of 89.47% for PA via ADC [25]. Similarly, another study reported a slightly lower SEN (84.6%) and SPE (80%) to distinguish MB and PA, utilizing DWI [26].…”
