1. Longitudinal whole-brain analysis of multi-subject diffusion data in diffuse axonal injury
RESUMO Antecedentes: A lesão axonial difusa ocorre em traumas com alta energia de aceleração e desaceleração, determinando desorganização da microestrutura cerebral, levando a algum déficit. A escala de Glasgow Estendida (GOS-E) é indicada na avaliação clínica das vítimas de trauma cranioencefalico. Imagens por tensor de difusão (DTI) estudam

2. Biometric parameters of adult and growing Pêga donkeys
ABSTRACT This study aimed at establishing the morphological characteristics and morphometric indexes of Pêga donkeys, utilizing 47 animals, of which 22 were adults and 25 were growing donkeys. Prior to taking their measurements, the animals were restrained and made to stand squarely. The morphological data were measured, and the following morphometric index

4. Contribuição atual da imagem por tensor de difusão na avaliação da lesão axonal difusa
RESUMO O traumatismo cranioencefálico (TCE) é a principal causa de morbimortalidade entre adultos jovens. Aqueles que sobrevivem são frequentemente deixados com sequelas funcionais nos anos mais produtivos de suas vidas. O principal aspecto fisiopatológico do TCE é a lesão axonial difusa (LAD), cada vez mais destacada pois está presente em 40 a 50% do

5. UM PAINEL DE CARACTERÍSTICAS CLÍNICAS E NEUROPATOLÓGICAS DA DOENÇA CEREBROVASCULAR ATRAVÉS DOS NOVOS MÉTODOS DE NEUROIMAGEM
RESUMO. A última década vem testemunhando avanços substanciais na aquisição de marcadores biológicos para o diagnóstico da doença cerebrovascular (DCV). Os métodos de neuroimagem avançados não apenas fornecem uma contribuição estratégica para o diagnóstico diferencial do comprometimento cognitivo vascular (VCI) e demência vascular (VaD), mas

7. Enhancing quality in Diffusion Tensor Imaging with anisotropic anomalous diffusion filter
Abstract Introduction: Diffusion tensor imaging (DTI) is an important medical imaging modality that has been useful to the study of microstructural changes in neurological diseases. However, the image noise level is a major practical limitation, in which one simple solution could be the average signal from a sequential acquisition. Nevertheless, this approac

8. Populational brain models of diffusion tensor imaging for statistical analysis: a complementary information in common space
Abstract Introduction: The search for human brain templates has been progressing in the past decades and in order to understand disease patterns a need for a standard diffusion tensor imaging (DTI) dataset was raised. For this purposes, some DTI templates were developed which assist group analysis studies. In this study, complementary information to the most

10. Development of a new HPLC method for in vitro and in vivo studies of haloperidol in solid lipid nanoparticles
ABSTRACT A simple and sensitive HPLC method was developed and validated for the quantification of haloperidol in solid lipid nanoparticles (SLNs). The developed method was used for detection of shelf life of haloperidol in SLNs. Calibration curve of haloperidol was also constructed in rat plasma using loratidine as internal standard. In vivo studies were per

11. Phantoms for diffusion-weighted imaging and diffusion tensor imaging quality control: a review and new perspectives
Abstract: Introduction Diffusion-weighted imaging (DWI) and diffusion tensor imaging (DTI) combine magnetic resonance imaging (MRI) techniques and diffusion measures. In DWI, the contrast is defined by microscopic motion of water protons. Nowadays, DWI has become important for early diagnostic of acute stroke. DTI images are calculated from DWI images acqui

12. Usefulness of diffusion tensor imaging in amyotrophic lateral sclerosis: potential biomarker and association with the cognitive profile
ABSTRACT The objective of this preliminary study was to correlate diffusion tensor imaging (DTI) alterations with the cognitive profile of patients with amyotrophic lateral sclerosis (ALS). Methods This was a case-control study conducted from December 1, 2012 to December 1, 2014. Clinical and demographic data were recorded. A neuropsychological test batter
