Principles of magnetic resonance imaging

Abstract

This chapter focuses on the principles of magnetic resonance imaging (MRI) from the perspective of nonphysicists and clinical users. Magnetic resonance (MR) is a collection of techniques that enables many aspects of the structure, biochemistry, and function of the brain to be identified completely and noninvasively. The general principle of generation of an MR image is that if a lesion is not seen on a particular MR study, it does not mean that it cannot be seen through other MR techniques. The chapter discusses some basic principles of MR physics. The noninvasive nature and high spatial resolution of MR techniques hold great promise for the investigation of many aspects of brain functions, ..
