Elaboração de um protocolo de ressonância magnética para exames de coluna cervical em pacientes que utilizam aparelhos ortodônticos

Abstract

Objective: The purpose of this study is to highlight the development of an MRI protocol for cervical spine exams in patients using fixed orthodontic appliances. Methodology: We performed tests on a simulator objects created for the research and the researcher for the fact of being a fixed orthodontic appliance, using the protocol provided by the clinic for cervical spine examination and after making modifications in parameters for the reduction of distortion Geometric Results: The results of the studies demonstrated the possibility of real reduction of the magnetic susceptibility artifacts caused by the use of orthodontic appliances. Conclusion: The creation of a properly adjusted protocol for patients using fixed orthodontic appliances that could prevent the inconvenience of pausing orthodontic treatment for a few days and the imaging service would save on the possibility of client return. Because this study would help patients perform cervical spine MRI scans, by adjusting the parameters so that it is adequate. Thus creating in protocol properly adjusted for patients who use fixed orthodontic appliances. As a methodology, tests were performed with the purpose of reducing the magnetic susceptibility artifact caused by fixed orthodontic appliances.
