ABSTRACT

Brain imaging, as a field within biomedical engineering, is in a perpetual state of development, and an exhaustive review of all imaging modalities cannot be provided. Rather, this chapter will focus on those modalities that have shown the greatest promise for clinical utility in neurological and psychiatric disorders – magnetic resonance imaging (MRI), single photon emission computed tomography (SPECT), and positron emission tomography (PET). More than understanding the engineering or physics that underlies each technology, it is the biological correlates of imaging that are of greater importance to us, as they dictate the clinical utility of each imaging approach.
