Introduced by Lingfeng Zhang et al. in A Novel Center-based Deep Contrastive Metric Learning Method for the Detection of Polymicrogyria in Pediatric Brain MRI22 Nov 2022 archive 2025-07-28

This dataset contains 23 patients in total. Within each patients MRI, not all images show evidence of PMG and some slices are normal. Although the ratio between controls and patients is 3:1, the ratio between normal slices and anomaly slices is around 5:1. Each patient’s brain includes around 150 scans on average.
