Estudo da técnica de ressonância magnética para algumas aplicações voltadas à neurologia e à neurociência

Magnetic resonance imaging (MRI), which is studied since 1938, is a technique used in medicine to produce high quality images from inside the human body. These images are produced non-invasively and without ionizing radiation. In addition, MRI is an extremely flexible technique, with which it is possible to produce images with different contrasts that provide different information about the anatomy, structure and function of the human body, and it is therefore one of the techniques preferred by radiologists. The phenomenon of MRI is based on the interaction of magnetic fields with the nuclear spins of the scanned sample. In this work a detailed study of the technique of magnetic resonance imaging is presented, with a description of the main features of the images produced by the technique and an analysis of its application to the fields of applications Neurology and Neuroscience

Angiografia comparativa, prós e contras entre os métodos: por raios-X, Tomografia Computadorizada e Ressonância Magnética

By the early 20th century, the blood vessels could only be seen by anatomical studies. Shortly after the discovery of X-rays by Conrad Roentgen in 1895, the first experiments with radiographic imaging were performed with blood vessels. In 1905, the first experiment involving catheterization of arterial and venous system in dogs was performed and only in 1914 performed on living human patients. Parallel to these landmarks, there were advances in diagnostic imaging devices and the evolution of contrast substances was of utmost importance to the current angiography occupy a prominent role not only in terms of diagnosis, but also in the treatment of various disorders. The main objective of this review is to weave historical considerations and comparisons between the different methodologies used in angiography, because its importance; that may be in future, a veterinary diagnostic decisive test

Estabelecimento do contraste entre as fricativas por crianças com transtorno fonológico: manipulação de pistas acústicas

The present study focuses on the presence of covert contrasts in the speech of children with a phonological disorder. The hypothesis is that children with phonological disorders manipulate secondary acoustic cues in an attempt to distinguish the phonological contrasts. We used five audio recordings of the speech of five children with speech disorders, between four and five years of age, who showed the so-called “phonic substitution” involving the sound group of the fricatives. The data were edited and analyzed using the software PRAAT. A phonetic transcription of the first repetition of each child was performed by three evaluators, reaching a 66% agreement level. After the transcription, we carried out a contrastive phonological analysis of the production of the five children and, finally, an acoustic analysis of all the “substitutions”, based on six parameters. We discovered the existence of covert contrasts in the productions auditorily regarded as homophones by the evaluators, representing a total of 54% of total substitutions identified through an impressionistic approach by the evaluators. Children with phonological disorders are seen to rely on secondary acoustic cues in an attempt to distinguish fricative phonemes. The data obtained in this study allow us to reflect on the importance of considering the phonetic detail within the phonological models.
