About the 7-TLE study
- The 7-Tesla Temporal Lobe Epilepsy (7-TLE) Study is a prospective, case-control neuroimaging study of both children and adults with TLE being considered for epilepsy surgery.
- The 7-TLE Study utilises the ability of the high-field, 7-Tesla MRI scanner at St Thomas’ Hospital (find more details here) to obtain high-resolution data of small structures (such as the piriform cortex) in the temporal lobe.
- The 7-TLE Study will primarily investigate the connectivity of the piriform cortex and mesial temporal lobe structures by comparing functional MRI measures between patients with TLE and healthy participants.
Design
- Participants are invited to attend a single visit during which they will have a single 7-Tesla MRI scan.
- We are performing high-resolution functional and diffusion MRI to investigate the brain connectivity of temporal lobe structures.
- We are also developing the use of electroencephalography (EEG) to run simultaneously with fMRI acquisition
Objectives
