Fetuses with VM had distinct sulcal positional developmental patterns compared to control. Similarity analyses of left hemisphere (a, b) and right hemisphere (c, d) were presented. Similarity indices of combined feature (a, c) and sulcal position (b, d) were compared between fetuses with VM and controls using t-test. Similarity indices were compared as all sulci in a hemisphere as a whole, matched corresponding sulci, and the inter-sulcal relationships. In the left cerebral hemispheres, fetuses with VM had lower similarity indices in sulcal position and combined feature. In the right cerebral hemispheres, no differences were seen in sulcal developmental patterns. * Significance p-value <0.05.
