Postprocessing of MRIs Using FreeSurfer in Epilepsy Surgery Patients Provides an Excellent Imaging Marker of Hippocampal Sclerosis but Fails to Separate Subtypes

Figure 2

Violin plot displaying distributions of volume asymmetry ratios with overlaying data points in all four groups across the four hippocampal regions. For each of the three hippocampal regions (WH, CA1, and CA4), the distribution of volume asymmetry ratios for each patient group and the healthy controls is represented by a violin shape. The shape outline represents a kernel density estimate of the data for each group with overlaying data points. Within the center of each violin, the white dot represents the median value, and the grey line represents the 25^th and 75^th percentiles. HS = hippocampal sclerosis; HC = healthy controls; Std = standard deviations; WH = whole hippocampus; CA = cornu ammonis; ILAE = International League Against Epilepsy.
