There are probably cases where an MRI and/or MRS triggers epileptic seizures directly, and/or lowers the seizure threshold compatible with another lowering threshold resulting in an epileptic seizure hours later. The last two have been to determine if a seizure focus can be identifed. If a clear reason for seizures is not found on MRI, this might exclude the patient from surgery unless other tests, such as EEG, PET or MEG, can identify a seizure focus. Diffusion-weighted and perfusion MRI demonstrates parenchymal changes in complex partial status epilepticus. It is important to realize that these triggers increase the likelihood of an event but do not immediately result in a seizure.

In addition, the topography of SCM was as follows; i) ipsilateral hippocampus, thalamus and cerebral cortex (5/11), ii) unilateral cortex (4/11), iii) ipsilateral thalamus and cerebral cortex (1/11), iv) bilateral hippocampus (1/11). During the test, several dozen images may be obtained. EEG can show unusual electrical activity patterns. Febrile seizures can be frightening, but nearly all children who have a febrile seizure recover quickly. Since the MRI, I have had an increase of seizures.
