“…Fox et al, 2001). All these efforts draw on methods from the rapidly growing field of computational anatomy (see e.g., Ashburner et al, 2003;Bankman, 1999: Bookstein, 2001: Chung, 2001: Csernansky et al, 1998Davatzikos, 1996Davatzikos, , 2001Drury and Van Essen, 1997;Evans et al, 1994;Fischl and Dale, 2000;Fitzpatrick and Sonka, 2000;Gee and Bajcsy, 1998;Gerig et al, 2001;Grenander and Miller, 1998;Leahy and Insana, 2001;Miller et al, 2002;Sereno et al, 1996;Thompson and Toga, 2003a,b;Thompson et al, 2000a,b, 2001a,b, cf.

This paper describes algorithms that can identify patterns of brain structure and function associated with Alzheimer's disease, schizophrenia, normal aging, and abnormal brain development based on imaging data collected in large human populations. Extraordinary information can be discovered with these techniques: dynamic brain maps reveal how the brain grows in childhood, how it changes in disease, and how it responds to medication. Genetic brain maps can reveal genetic influences on brain structure, shedding light on the nature-nurture debate, and the mechanisms underlying inherited neurobehavioral disorders. Recently, we created time-lapse movies of brain structure for a variety of diseases. These identify complex, shifting patterns of brain structural deficits, revealing where, and at what rate, the path of brain deterioration in illness deviates from normal. Statistical criteria can then identify situations in which these changes are abnormally accelerated, or when medication or other interventions slow them. In this paper, we focus on describing our approaches to map structural changes in the cortex. These methods have already been used to reveal the profile of brain anomalies in studies of dementia, epilepsy, depression, childhoodand adult-onset schizophrenia, bipolar disorder, attention-deficit/ hyperactivity disorder, fetal alcohol syndrome, Tourette syndrome, Williams syndrome, and in methamphetamine abusers. Specifically, we describe an image analysis pipeline known as cortical pattern matching that helps compare and pool cortical data over time and across subjects. Statistics are then defined to identify brain structural differences between groups, including localized alterations in cortical thickness, gray matter density (GMD), and asymmetries in cortical organization. Subtle features, not seen in individual brain scans, often emerge when population-based brain data are averaged in this way. Illustrative examples are presented to show the profound effects of development and various diseases on the human cortex. Dynamically spreading waves of gray matter loss are tracked in dementia and schizophrenia, and these sequences are related to normally occurring changes in healthy subjects of various ages.

“…Ao longo das últimas três décadas as imagens médicas sofreram uma revolução e para continuar se aprimorando, estudos e aplicações dos métodos de manipulação de imagens digitais foram essenciais (BANKMAN, 2000).…”

“…O termo imagem digital faz referência a todos os tipos de sistemas de imagens digitais, diretos ou indiretos (radiografia computadorizada, radiografia escaneada e radiografia fotografada) (BANKMAN, 2000;GONZALEZ;WOODS, 2000;COMPAGNONE et al, 2006;PRINCE;LINKS, 2006;TAGASHIRA et al, 2007;WIDMER, 2008;BOVIK, 2009;AMBRUST, 2010;THRALL, 2010;BUSHBERG et al, 2012). Os elementos da matriz digital podem ser chamados de elementos da imagem ou elementos da figura, termos traduzidos de picture elements, todavia suas abreviações pixels ou pels são mais utilizadas no cotidiano (BANKMAN, 2000;GONZALEZ;WOODS, 2000;PRINCE;LINKS, 2006;BOVIK, 2009;BUSHBERG et al, 2012).…”

“…Os sistemas digitais utilizam programas de computador que permitem a manipulação dos dados gerados na aquisição da imagem (BANKMAN, 2000;GONZALEZ;WOODS, 2000;BANSAL, 2005;PRINCE;LINKS, 2006;WIDMER, 2008;BOVIK, 2009;AMBRUST, 2010;BUSHBERG et al, 2012). A principal vantagem dos sistemas digitais é o processamento da imagem radiográfica após sua aquisição (POLUNIN; LIM; TAN, 1998;PROKOP et al, 2003;BANSAL, 2005;DROST;HORNOF, 2008;MAROLF et al, 2008;PUCHALSKI;LO, 2008;WIDMER, 2008;ONISHI, 2009;AMBRUST, 2010;REESE et al, 2011), isso por meio de recursos adicionais, tais como: adequação de brilho e contraste, aplicação de diversos filtros, mensuração de estruturas, cálculo de ângulos e inversão de posições (PROKOP et al, 2003;PUCHALSKI;LO, 2008;AMBRUST, 2010;REESE et al, 2011).…”

AGRADECIMENTOSÀ minha Família, muito obrigada pelo carinho, por me proporcionarem o suporte necessário para a realização dos meus sonhos e me acompanharem em todos os momentos da minha vida.Em especial, agradeço a um amigo querido que me guiou em meio aos labirintos que passei.Confiança e estímulo eram o básico que se encontrava por trás da porta com a placa: Sala do Prof. Dr. Franklin de Almeida Sterman. Nos momentos especiais de atenção transbordavam conselhos profissionais e pessoais, todos absorvidos com muita intensidade e refletidos em forma de admiração, respeito e carinho e, na despedida das conversas, restava o sentimento ávido pela próxima lição de vida... Saudades! À minha orientadora, Profa. Dra. Ana Carolina Brandão de Campos Fonseca Pinto, agradeço pelo grande apoio, incentivo, confiança e amizade em todos esses anos de convívio. Admiro a dedicação que a senhora tem com os alunos, com a rotina hospitalar, com as disciplinas em que está envolvida e em especial, com o cuidado que tem com a sua família. Com certeza a senhora é um grande exemplo de mulher que conseguiu alcançar a igualdade com os homens, nos melhores quesitos de cada gênero e que luta diariamente para conseguir administrá-los de forma equilibrada. The transition of the conventional radiographic system to the digital one has been transforming the radiographic routine human and veterinary medicine over the last twenty years. Currently, the introduction of the computed radiography system in some hospitals and imaging services has increased the use of post processing tools. Considering the advantages and disadvantages of these tools and the lack of knowledge about the filters used in digital radiographic images, the aim of this study was to test efficacy of the standard, edge enhancement and gray scale reversed filters and their association to detect pulmonary patterns of cats and dogs. This work selected forty canine and feline sets of thoracic radiographs, including three projections. Three different observers with different degrees of experience and familiarity with the computed radiographic system analyzed the filters individually and then associated in order to detect pulmonary patterns. The best results in sensibility and specificity were related to the more experienced observers using the three associated filters. However, for the beginner, the best sensibility and specificity results was reached with the use of the standard filter in general results. In conclusion were statistical differences between more experienced and familiarized observers with the digital system and the use of filters can increase the radiologist performance when evaluating the pulmonary patterns on the radiography.
