Enhanced MRI Imaging in Healthy Participants and Participants With Epilepsy
Recruiting now Phase 2 NCT06483061
Run by University of Alberta · for 18 to 64 · All sexes · accepts healthy volunteers
What this study is about
Temporal lobe epilepsy (TLE) is a common type of epilepsy and one of the most likely to not be controlled by medication. For patients who do not respond to medication, surgery can result in a cure of seizures. Given the fact that around 50% of patients who undergo surgery are seizure free at 10 years there is a need to improve the understanding of what factors best predict surgical outcomes in order to improve our ability to select candidates for surgery. The demonstration of abnormalities in the temporal lobe on MRI is one of the best predictors of seizure free surgical outcomes. Recent studies suggest that changes in specific subregions of the hippocampus could be the strongest predictors of surgical success, however the small size of these regions, (millimeters) make them very difficult to study with standard clinical MRI. Recently new MRI methods have been developed at Wayne State University to image hippocampal blood vessels using ferumoxytol infusion. Feraheme (ferumoxytol) is a drug that is approved in the United States for the treatment of iron deficiency anemia and is currently being studied as an MRI contrast agent in 8 active clinical trials in the United States as well as a Parkinson's Disease study in Canada.
