This work is a resource that explains how to use techniques such as neuroimaging to improve outcomes. It provides practical advice on using the most advanced applications in the diagnostic workup of patients. It covers structural techniques such as computed tomography (CT) and magnetic resonance imaging (MRI), functional techniques such as position emission tomography (PET), single photon emission computed tomography (SPECT), functional magnetic resonance imaging (FMRI), and magnetic resonance spectroscopy (MRS). Other techniques covered are electroencephalography (EEG) - including quantitative EEG and event-related potentials - and magnetoencephalography. For each modality, you will find a review of the technique, trace the development of each modality, guidance on when to use it, learn which techniques are best to use in specific clinical situations, and tips for ordering studies.
