C C D 91 ResumenIntroducción: Las matrices de co-ocurrencia del nivel de gris (GLCM) son útiles para el análisis textural de imágenes ya la discriminación de patrones pero hasta ahora no se han aplicado sobre imágenes ecográficas del tendón. Objetivo: Análisis textural ecográfico del tendón rotuliano. Método: Estudio longitudinal analítico con 16 sujetos (8 mujeres y 8 hombres) jóvenes, sanos y sedentarios entrenados con una plataforma de vibración vertical (Fitvibe Medical) 2 días x 14 semanas. Se tomaron cortes ecográficos transversales del tendón rotuliano antes y después del entrenamiento con un ecógrafo Sonosite-180 (Lineal 5-10 MHz). Mediante el algoritmo GLCM de Image J v1.38 se calcularon las variables texturales Uniformidad (ASM), Contraste, Correlación, Homogeneidad (IDM) y la Entropía para cuatro orientaciones (0º, 90º, 180º y 270º) y tres distancias (d=1, 5 y 10 px). Se aplicó la prueba de Wilcoxon (i.c.95%) para muestras relacionadas (SPSS 15.0). Resultados: la Entropía (d=5) fue la más sensible a los cambios texturales; quizá la variable ASM, pueda resultar también de interés junto con el Contraste. Conclusiones: Ante la falta de referencias con el uso de la GLCM en el análisis textural de ecografía de tendón son necesarios más aná-lisis que estudien cómo afectan los distintos parámetros a las variables texturales, cómo se relacionan entre sí y cuáles pueden ser los mejores ajustes del algoritmo para detectar cambios en el patrón textural.Palabras clave: Matrices de co-ocurrencia de nivel de gris, textura, tendón ecografía, vibración de cuerpo completo. AbstractIntroduction: Co-occurrence grey level matrix (GLCM) is a textural analysis method that have been useful to discriminate patterns, but no used on tendon ultrasound image. Objective: Textural analysis of patellar tendon ultrasonograph. Method: Longitudinal analytic study with 16 subjects (8 women and 8 men) young, healthy and sedentary people with training by means wholebody vibration platform (Fitvibe Medical) for 2 days x 14 weeks. Cross-sectional of patellar tendon ultrasonographics were taken with a Sonosite-180 ultrasonograph (L 5-10 MHz). By means GLCM algorithm of Image J v1.38 it were calculated five textural parameters: Uniformity (ASM), Contrast, Correlation, Homogeneity (IDM) and Entropy in four orientations (0º, 90º, 180º and 270º) and three distances between pixels (d=1, 5 and 10 pixels). Wilcoxon test (C.I. 95%) for related samples was applied (SPSS 15.0). Results: Entropy (d=5) was the most sensible to detect textural changes; perhaps ASM and Contrast can be also useful. It seems that distances between pairs of pixels that the algorithm uses affects the results. Conclusions: The use of GLCM in the textural analysis of tendon ultrasonography is innovating and it appears like a useful tool as much to evaluate the histological evolution of tendon tissue, like coming up and detecting future pathologies precociously. But more analyses will be necessary to study how different parameters affect texture and how they are related to each...
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
