Examples

• Encephalography was once a standard diagnostic procedure for detecting brain tumors and abnormalities.
• The development of encephalography in the early 20th century represented a major advance in neuroimaging.
• Modern neurologists rarely use encephalography, preferring non-invasive MRI scans instead.
• The patient underwent encephalography to help locate the source of the seizures.
• Encephalography has been largely superseded by safer and more detailed imaging methods.
