Utilização do índice de resistência vascular na diferenciação entre nódulos mamários benignos e malignos

Abstract: OBJETIVO: O objetivo deste estudo foi avaliar o significado do Doppler espectral por meio da obtenção do índice de resistência vascular na diferenciação entre lesões mamárias benignas e malignas. MATERIAIS E MÉTODOS: Dezenove lesões malignas e 18 benignas, diagnosticadas por estudo histológico, foram submetidas previamente a análise de sua vascularização por meio do Doppler espectral para se obter o índice de resistência vascular. RESULTADOS: Observou-se diferença estatisticamente significante (p < 0,001) e… Show more

“…Considering this method applicability, it may be adapted to run with other image acquisition techniques such as elastography, for example, since the image texture parameter tends to change under compression of the area of interest (28) . Additionally, the present texture parameters may be combined with further quantitative parameters which represent other characteristics of lesions such as shape and contour (29) , or even the vascular resistance index obtained by means of Doppler ultrasound (30) .…”

“…Category 4 has been subdivided into 4A, 4B and 4C. All the categories must reflect the radiologist's level of suspicion for malignancy and correspond exactly to the possibility of malignancy confirmed by subsequent studies such as plain mammography, mammography with supplementary views, ultrasonography with or without Doppler, and magnetic resonance imaging (4,6,7) .…”
