Tomografía computarizada de doble energía: nueva tecnología para la reducción de artefactos de metal

Introducción: El objetivo fue explorar la utilidad de la tomografía computarizada de doble energía mediante tecnología de imágenes espectrales gemstone y de un programa destinado a la reducción de artefactos de metal (MARS), para evaluar tejidos periprotésicos, y la interpretabilidad diagnóstica ...

Applicability of the Cobb angle measurement in idiopathic scoliosis using scanned imaging

Coluna/Columna; 16 (1), 2017
ABSTRACT Objectives: To compare the measurement of the Cobb angle on printed radiographs and on scanned radiographs viewed through the software "PixViewer". Methods: Preoperative radiographs of 23 patients were evaluated on printed films and through the software "PixViewer". The same evaluator, a spi...

Reproducibility of Gadolinium Enhancement Patterns and Wall Thickness in Hypertrophic Cardiomyopathy

Arq. bras. cardiol; 107 (1), 2016
Abstract Background: Reproducibility data of the extent and patterns of late gadolinium enhancement (LGE) in hypertrophic cardiomyopathy (HCM) is limited. Objective: To explore the reproducibility of regional wall thickness (WT), LGE extent, and LGE patterns in patients with HCM assessed with cardiac m...

Patrón de lectura radiológica digital para la clasificación de imágenes compatibles con silicosis

Cienc. Trab; 18 (55), 2016
La silicosis es una enfermedad sin tratamiento. El programa de vigilancia de trabajadores expuestos a sílice está diseñado para detectarla lo más precozmente posible mediante una radiografía de tórax. A pesar de su rol fundamental, esta adolece de una gran variabilidad técnica y de interpretación...

Optical density evaluation around the zirconia granules used as graft in rat calvaria

Acta sci., Health sci; 36 (2), 2014
The aim of this study was to evaluate the optical density of the zirconia granules used as a graft in a rat calvarium model. Forty animals (Rattus Novergicus, albinus, Wistar) were divided into control and experimental groups and submitted to bone detects in the cranial cap using a trephine type burr 6 m...

Digital evaluation of the influence of interruption of the fixation process on radiographic contrast and base-plus-fog density in three commercial brands of radiographic films

Introduction : With the interest in anticipating access to the result of intraoral radiography, the radiographic processing is frequently neglected, compromising image quality. Objective: The aim of this study was to evaluate the influence of interrupting the fixation process on the radiographic contrast...

Desenvolvimento e aplicação de biomateriais à base de quitosana para reconstrução óssea: avaliação radiográfica e histológica

O objetivo desta pesquisa foi desenvolver biomateriais à base de quitosana e de cloridrato de quitosana (géis), e avaliar radiográfica e histológicamente seu uso na correção de defeitos ósseos críticos na calvária de ratos. Para tal, defeitos de 8mm de diâmetro foram criados cirurgicamente na c...
