An appropriate angle must be given in the axial plane (perpendicular to mid line of the brain). MRI collects structural information and creates images of the brain by using a large magnet. Advanced imaging techniques are needed to detect the location of the epileptogenic zone. This requires thinner slices, with voxel volumes of 1 mm 4 being the current norm at 3T, which improves spatial resolution but also increases scan time and noise. We explored the diagnostic value of oxygen-enhanced MRI, a novel technique for measuring regional brain metabolism, in a set of normal adult volunteers and temporal lobe epilepsy patients. 2.
