Lesion volume and spike frequency on EEG impact perfusion values in focal cortical dysplasia: a pediatric arterial spin labeling study.

In the univariate analysis, smaller FCD volumes showed a statistical trend of being correlated with higher AI values after controlling for age at MRI (Spearman’s correlation: − 0.48, p = 0.05, Fig. 2 B), whereas other epilepsy-related or lesion-related features were not related to AI values (Table 4 ).
