Gadolinium is not required 5. T2 relaxometry may also be useful in detecting cases of hippocampal sclerosis 5. Diffusion MRI As a result of neuronal loss, the extracellular space is enlarged and thus diffusion of water molecules is greater on the affected side, resulting in increased values on the affected side higher signal on ADC.
Conversely, due to neuronal dysfunction and swelling, diffusion is restricted following a seizure, and thus values are lower 5.
During the peri-ictal phases, perfusion is increased, not only in the mesial temporal lobe but often in large parts of temporal lobe and hemisphere. Treatment and prognosis TLE is initially managed medically with anti-epileptic agents. In patients who are refractory to medical management temporal lobectomy or selective amygdalohippocampectomy may be performed. Shinnar S. Febrile Seizures and Mesial Temporal Sclerosis.
