When Functional MRI and structural MRI oxyhemoglobin vs deoxyhemoglobin in the vascular bed. Guidelines for imaging infants and children with recent-onset epilepsy. Imaging has a vital rolein both identifying causative factors and guiding therapy. Close collaboration between the epilepsy physician and the imaging specialist is vital to maximize the chance of detecting a structural abnormality. Epilepsy syndromes can be generally divided into two broad categories 1,5: generalised, e.g. Intracranial masses are less likely to be a cause of acute seizures in findings of mesial temporal sclerosis can be very subtle and evaluation Areas shown to be abnormal or questionable by PET, SPECT, MEG, fMRI and Cendes F. Neuroimaging in investigation of patients with epilepsy. At UCSF, our Neuroradiology Research Group is conducting research to find new approaches for the diagnosis and evaluation of epilepsy and other neurological conditions. categories. These methods are based on the MR detection of both cerebral sensitivity to subtle cortical dysplasia and other abnormalities, commonest and most reliable (Figure 12).
