Neuroimaging




MRI
An image created with MRI
Neuroimaging procedures, especially MRI techniques, are essential tools for investigating the causes of seizure disorders. Improvements in MRI have enabled the detection of subtle anatomical lesions in patients previously regarded as having unexplained epilepsy. In people who are candidates for surgical treatment, detection of such subtle lesions, in combination with physiological data from EEG monitoring and PET scanning, results in more reliable localization of the seizure site. Another new technique, functional MRI, has the potential to locate essential functions that must be spared in surgical resection. In the future, functional MRI may reduce the need for more invasive techniques of functional mapping such as cortical stimulation, evoked potentials, and Wada angiography. Neuroimaging will continue to be one of the most important areas of epilepsy research in the next decade.
