High-resolution Multi-parametric Magnetic Resonance Imaging for Focal Epilepsy

Who May Qualify: - Consecutive patients with drug-resistant focal epilepsy fulfilling the following criteria - 1\. Diagnosis of focal epilepsy with a probable site identified, as defined by concordant results from any TWO of the following: - Clinical seminology compatible with focal epilepsy. - Electroencephalography pointing towards a specific site for focal epilepsy. - Positive ictal brain scintigraphy with SPECT-CT correlation. AND 2. Previous MRI (at least one study with protocol tailored for epilepsy) which did not reveal accountable focal lesion. AND 3. Able to consent for MRI examination (if patient under age of 18, consent for MRI will be obtained from guardian). Patients will be provided information leaflets to read on, and written consent before taking part in this study and MRI examination. Who Should NOT Join This Trial: - Patients who are contraindicated to magnetic resonance imaging (such as due to underlying MRI incompatible metallic implants) - Patients who cannot cooperate for MRI scanning. - Patients show are unable to provide willing to sign a consent form. Always talk to your doctor about whether this trial is right for you.
