Braçadeira para o auxílio na punção venosa nos exames de ressonância magnética

Abstract

Magnetic Resonance Imaging (MRI), studied since 1938, is a diagnostic imaging method established in clinical practice and in increasing development. These images are produced non-invasively and without the use of ionizing radiation. Furthermore, MRI is an extremely flexible technique, with which it is possible to produce images with different contrasts and that provide different information about the anatomy, structure and function of the human body, being, therefore, one of the preferred techniques by radiologists. The MR phenomenon is based on the interaction between magnetic fields and nuclear spins, since topics such as electromagnetism, superconductivity and signal processing must be addressed together. Because of this, there are few materials that are compatible with MRI and in this work, a design and construction of a prototype that is safe, stable for MRI and comfortable for the patient, will be presented, a cuff with support, which serves as a support for the exams that are carried out. need venipuncture and the use of contrast. The project first went through the Ethics Committee of the Federal Technological University of Paraná and was approved. And to ensure that the material was compatible with MRI, a test was carried out in two clinics in Curitiba and the result was satisfactory.
