The authors describe the fundamentals of magnetic resonance imaging (MRI), including image acquisition, the first image reconstructions employing filtered back projection, and modern Fourier imaging. They also review the genesis of image contrast for various imaging protocols as well as the use of exogenously administered contrast agents. Finally, they briefly compare MRI with other imaging modalities.
