AbstractLingual thyroid is an uncommon developmental aberrationof embryogenesis. It may present as a mid-line, non-tender, painless, reddish appearing swelling in the throat. Magnetic resonance imaging (MRI) is a relatively new diagnostic method for this condition. Two cases of lingual thyroid are reviewed with their MRI's and surgical results.

Analisar Este estudo tem o objetivo de apresentar as características, particularidades e aplicações variadas do exame de ressonância magnética no diagnóstico da esclerose múltipla (EM), apresentando suas vantagens e desvantagens no diagnóstico diferencial destas afecções. Está delineado pela proposta de uma pesquisa embasada nos pressupostos da revisão da literatura. Com isso, utilizou para análise estudos que tenham sido publicados em periódicos nacionais e internacionais, indexados em base de dados como BIREME e SCIELO, que tenham como enfoque principal a questão que envolve os critérios para a importância da ressonância magnética como método diagnóstico. Com o resultado da pesquisa foi possível concluir que o papel do diagnóstico por imagem na investigação da EM se mostra de muita importância, visto que apenas com a investigação clínica não é possível ter a certeza desta patologia se mostrando, então, como um importante instrumento auxiliar na detecção dos estágios iniciais e avançados da doença, permitindo a visualização das imagens e dos processos inerentes à patologia em questão.Descritores: Ressonância Magnética, Esclerose Múltipla, Diagnóstico. Diagnosis of multiple sclerosis by magnetic resonance imagingAbstract: This study aims to present the characteristics, particularities and varied applications of magnetic resonance imaging in the diagnosis of multiple sclerosis (MS), presenting its advantages and disadvantages in the differential diagnosis Of these affections. It is delineated by the proposal of a research based on the assumptions of the literature review. Thus, studies that have been published in national and international journals, indexed in databases such as BIREME and SCIELO, have been used to analyze the main focus of the issue that involves the criteria for the importance of magnetic resonance as a diagnostic method. With the result of the research it was possible to conclude that the role of imaging diagnosis in the investigation of EM is very important, since only with clinical research it is not possible to be sure of this pathology showing, then, as an important auxiliary tool to detect the early and advanced stages of the disease, allowing the visualization of the images and processes inherent to the pathology in question.Descriptors: Magnetic Resonance Imaging, Multiple Sclerosis, Diagnosis.Diagnóstico de la esclerosis múltiple por resonancia magnéticaResumen: Este estudio pretende presentar las características, particularidades y variadas aplicaciones de la resonancia magnética en el diagnóstico de la esclerosis múltiple (EM), presentando sus ventajas y desventajas en el diagnóstico diferencial de estos afectos.

Aim.To evaluate the role of magnetic resonance imaging (MRI) as a diagnostic method in children with acute trauma of the cervical spine and spinal cord, to compare the correspondence of MRI results with neurologic symptoms in accordance with the ASIA scale.Materials and methods.156 children with acute trauma of spine and spinal cord at the age from 6 months up to 18 years were studied. MRI was performed on a Phillips Achieva 3T scanner. The standard protocol included MYUR (myelography) in coronal and sagittal projections, STIR and T2VI FS SE in sagittal projection, T2VI SE or T2 * VI FSGE (axial projection), 3D T1VI FSGE before and after contrast enhancement. Contrast substance was injected intravenously in the form of a bolus at the rate of 0.1 mmol/kg (equivalent to 0.1 ml/kg) at a rate of 3 to 4 ml.Results.The causes of cervical spine blunt trauma were: road accidents (55), catatrauma (60), “diver” trauma (21), blunt trauma (20). Intramedullary lesions of the spinal cord were detected: concussion (49), bruising / crushing (27), hematomia (34), disruption with divergence of segments (21), accompanied by edema (141); extramedullary lesions: epi- and subdural, intralesive and sub-connective and soft tissues hematomas (68), ruptures of bundles (48), fractures (108), dislocation and subluxation of the vertebrae (35), traumatic disc herniation (37), spinal cord compression and/or rootlets (63), statics violation (134), instability (156).Conclusion.MRI is the optimal method for spinal cord injury diagnostics. In the acute period of injury this technique has limited application, but it can however serve as a primary diagnostic method in these patients. MRI should be performed no later than the first 72 hours after injury. The most optimal for visualization of cervical spine trauma and spinal cord are T2VI SE and STIR in sagittal projection with suppression of signal from fat. MRI results correlate with neurologic symptoms at the time of performance according to the ASIA scale, and therefore MRI should be performed in all patients with acute cervical spine trauma, whenever possible.
