Devices and Materials in MRI

摘要: Magnetic resonance imaging (MRI) provides superiorvisualization of morphology, biochemistry, and physiology through differently weighted soft tissue contrasts (T 1 , T 2 fat or water suppression, etc.). In addition, its high flow sensitivity depicts functionalaspects such as blood flow, perfusion, diffusion organs. The physical nature MRI three-dimensional, spatially defined image volumes which allow guidance automatic slice orientation well device localization (tip tracking). Therefore, magnetic (MR) safety compatibility are important issues for all items, including implants, surgical tools, electronic mechatronic equipment, to be used within an MR environment. testing medical devices is required approval by regulatory agencies, e.g., the Food Drug Administration (FDA) European Union (EU) Notified Bodies.
