"In general, MR spectroscopy demonstrates a decrease in NAA/Cr ratio in the heterotopic grey matter compared to normal control subjects. It is important to note that comparing the spectrographic trace to the 'normal-appearing contralateral side' is not necessarily valid as control as metabolic abnormalities in patients with malformations of cortical development may be widespread 7."
"fMRI (BOLD imaging) can demonstrate activation in heterotopic nodules and these can match epileptogenic EEG discharges 8."
