Neuroimaging is a field of medicine that deals with the diagnosis and treatment of neurological disorders. Neuroimaging includes the use of various imaging modalities such as computed tomography (CT), magnetic resonance imaging (MRI), positron emission tomography (PET), and single-photon emission computed tomography (SPECT).
Some of the emerging trends in neuroimaging include the use of functional magnetic resonance imaging (fMRI) to study brain activity, the use of diffusion tensor imaging (DTI) to study the structure of the brain, and the use of positron emission tomography (PET) to study the function of the brain.
