Practically every innovation in magnetic resonance imaging (MRI) has been applied first to the brain. The brain's well-defined anatomy, MR characteristics, and relative absence of motion make it ideal for MRI. Advances in hardware, such as higher field strengths, high performance gradients, and advanced coil designs have led to brain scans with more contrast obtained at higher speeds. Pulse sequence advances such as echo planar imaging, fluid attenuated inversion recovery, diffusion weighted, perfusion imaging, and spectroscopic images have expanded the diagnostic range of MRI. Image processing and image management have also had a profound impact on MRI of the brain. This chapter reviews these developments and provides illustrative examples.
