Diffusion tensor imaging (DTI) was used to delineate early laminar organization of the cerebrum in two extremely premature infants imaged postnatally at estimated ages of 25 and 27 menstrual weeks. The diffusivity and anisotropy of the cortical plate, subplate zone, intermediate zone, subventricular and periventricular zones, and germinal matrix are examined. Automated segmentation of diffusion tensor images to reveal the laminar architecture of the developing human cerebrum is also demonstrated.
弥散张量成像（DTI）用于描绘两名极早产儿出生后的大脑早期分层结构，这两名早产儿估计的月经龄分别为25周和27周。研究了皮质板、亚板层区、中间区、脑室下和脑室周围区以及生发基质的扩散率和各向异性。还展示了通过自动分割弥散张量图像来揭示发育中人类大脑的分层结构。
