Advances in MRI Methodology

Abstract

Magnetic resonance imaging (MRI) is a non-invasive technique which can provide comprehensive, multi-parametric information on brain anatomy, function and metabolism. This chapter will give a brief introduction to the basic principles of MR and cover the evolution of image acquisition. Given the versatility of MR, a vast range of MR applications will be discussed, including structural, diffusion tensor, functional, perfusion and neuromelanin-sensitive imaging, as well as quantitative susceptibility mapping. This chapter will also cover methodological developments in MRI, including image analysis approaches that can be tailored according to experimental design or aims. The ultimate goal of this chapter is to equip readers with a fundamental understanding of the proficiencies and limitations of MR techniques and their corresponding analysis approaches.
