“…On the other hand, in T2-weighted images, there is a greater contrast ratio between tissues when using long TR and TE. For the anatomy of regions that concentrate a greater amount of liquid, it will be visualized with hypersignal (higher signal intensity), whereas fat will present hyposignal, that is, lower signal intensity [6].…”

Magnetic Resonance Imaging (MRI) is an exam that portrays morphological structures through high-definition images using a magnetic field. Understanding the physical basis of MRI represents a challenge for students in diagnostic imaging, as it involves advanced and complex technology. Here, we discuss image acquisition parameters, demonstrating advantages and disadvantages in using different values for each variable addressed and their impact on the quality and resolution of images obtained from the morphological study of tropical fruits. Based on the analysis of images of fruits submitted to MR scanning, we investigated the advantages and disadvantages of using different values for the field of view, slice thickness, matrix, and the use of different weights for scanning, measuring the resolution and quality of the images obtained. It was found that the use of fruit scanning represents an excellent tool for the development of students in radiodiagnosis, aiming at understanding the parameters used in the protocols for acquiring MR equipment and optimizing the quality of images.

“…Apresenta maior incidência em países da Europa e América do Norte (Dobson & Giovannoni, 2019). No Brasil, estudos mostram diferentes padrões de prevalência entre as regiões do país, sendo que a doença no estado de Goiás apresentou significativo aumento no número de diagnósticos nos últimos anos, o que pode estar relacionado ao maior conhecimento e treinamento dos profissionais para a detecção (Ribeiro et al, 2019;Araújo et al, 2020;Gabardo et al, 2020;Ribeiro et al, 2021;Ribeiro et al, 2022).…”

A Esclerose Múltipla (EM) é uma doença crônica degenerativa que atinge o sistema nervoso central. O tratamento visa a diminuição do processo inflamatório e retardar o avanço da doença. Este trabalho analisa as opções terapêuticas existentes e atualmente disponíveis para o tratamento de pacientes com esclerose múltipla. Foi realizado um estudo epidemiológico, a partir de uma revisão integrativa dos dados disponíveis no PubMed, SciELO e Google Acadêmico, utilizando os descritores “esclerose múltipla” e “tratamento”. A terapia farmacológica para EM pode ser empregada para tratamento sintomático, de episódios agudos/surtos, ou pela utilização de medicamentos modificadores da doença. A variedade existente de medicamentos modificadores da doença permite flexibilidade na escolha da melhor opção de acordo com o perfil de cada paciente. Aliando-se aos tratamentos medicamentosos, terapias complementares são importantes para a neuroreabilitação e controle de sintomas, como a psicologia, fonoaudiologia, neuropsicologia, fisioterapia e terapia ocupacional. Outros pontos recentemente discutidos no tratamento da EM são a utilização complementar de vitamina D, o uso de compostos canabinoides, e uma perspectiva futura do transplante autólogo de células tronco. Considerando a prevalência e impacto da EM sobre a qualidade de vida dos pacientes a longo prazo, a importância do diagnóstico e início do tratamento precoce, bem como a busca por novas evidências para o melhor manejo terapêutico possível da EM são fundamentais para a qualidade de vida do paciente.

“…The literature shows that magnetic resonance imaging (MRI) and computed tomography (CT) are the radiodiagnostic exams to help the clinical evaluation and subsequent diagnosis of this pathology. MRI is considered the gold standard exam for identification and analysis of CA (Araújo et al, 2020;Joaquim, 2020;Jesus, 2018).…”

Chiari's malformation is within the spectrum of congenital abnormalities of the central nervous system (CNS). It is characterized by a complex deformity of the posterior fossa associated almost always with a malformation of the spine. Chiari malformation is still a subject of little evidence in literature, where new studies on this parameter may trigger influences for researchers in the field. The objectives of this study were to describe the main alterations found in the nervous system in individuals with Chiari malformation. It is a literature review study. The following descriptors were used for the search: Chiari malformation, Posterior Pit and Craniovertebral Junction (together and separately). In the selection criteria, full articles were chosen for the period: 2016 - 2019, in the languages: Portuguese and English. The searches were made in the databases: Scielo, Pubmed and Google academic. The articles were selected first by title, then by abstract, and finally by full reading. Based on the established criteria, 3 articles were selected that contemplate the theme. The literature shows that the most suggestive brain alterations of this pathology are cerebellar abnormalities such as caudal displacement of the bridge, IV ventricle and bulb; medullary torsion; IV ventricle in abnormal shape and hypoplasia of the cerebellum tent and mesencephalic ceiling. It is noticeable that Chiari's malformation can cause alterations that can vary from lighter to more severe. New studies are needed on this subject, as well as solutions to improve the quality of life of patients affected by this syndrome.
