Objetive: assess the ultrasound characteristics of neonatal thalamic damage (hemorrhage or infarction) and the associated prenatal factors.  Material and methods: it’s a retrospective descriptive study of a series of neonates’ cases with thalamic damage. We review the data of the ultrasound report from 3 562 neonates, since august 1999 until august 2004. The transfontanellar ultrasound studies were performed in the Diagnostic Imaging and Neonatal Intensive Care Services. An ultrasound equipment with micro-convex transducer of 5 and 7.5 Mhz was used. Results: there were 8 (0,2%) cases of thalamic damage: 6 unilateral and 2 bilateral, 5 in preterm neonates and 3 in term neonates. The average weight of the preterm newborns was 1,490 gr, and in the term newborns was 3,210 gr. The average gestational time in newborns was 30,4 weeks and 39,3 weeks for the term ones. The prenatal fa...

Se realiza una revisión completa y actualizada de las características ecográficas de las lesiones benignas, malignas, cáncer de mama, clasificación ecográfica según la terminología BI-RADS (Breast Imaging Reporting and Data System), Doppler del Cáncer de mama, tridimensional (3D), metástasis ganglionar, ecografía como método de screening y biopsia de lesiones de mama mediante guía ecográfica. La revisión pretende brindar pautas que nos permitan determinar con mayor exactitud el cáncer de mama.En los últimos años la ecografía de mama, gracias al avance tecnológico de transductores de alta resolución lateral, imágenes armónicas, Doppler color, vistas panorámicas, uso de ecorrealzadores, tridimensionales, ha llegado a ser el examen de imagen mas importante en la evaluación complementaria a la mamografía de las lesiones mamarias y en muchos casos (mujeres con mamas ...
