摘要: Article abstract To elucidate the dynamics and nature of normal-appearing white matter (NAWM) changes preceding new lesion formation in MS, authors obtained weekly diffusion-weighted images for 12 weeks from 6 patients. NAWM areas subsequently involved by enhancement had a significant increase mean diffusivity values starting before appearance ( p ranging between
