Abstract

This chapter provides a brief introduction to the physics of magnetic resonance imaging (MRI) for undergraduate students. The first part of the chapter will introduce the reader to the basics of MRI including the MR imaging principle using a static magnetic field B0, radiofrequency field B1, gradient magnetic fields and MRI pulse sequences. The second part explains the MRI contrast parameters T1, T2, proton density ρ and T2 *. The third part describes physiological and functional MR imaging including cardiac MRI, Magnetic Resonance Angiography, perfusion MRI, functional MRI, diffusion weighted MRI and MR Spectroscopy. The focus of the fourth part is on MRI safety. The fifth part highlights future MRI applications such as Ultrahigh-Field MRI, Ultrafast sequences, MRI-guided interventions and Hybrid MR Imaging.
