Multimodal 7T MRI reveals subcortical structural, functional, iron accumulation, and glymphatic abnormalities in chronic migraine
Background Exploring the pathogenesis of chronic migraine (CM) remains a formidable challenge. While 7T MRI enables precise detection of microstructural alterations in subcortical nuclei and subregions in CM, comprehensive multimodal imaging studies are few. We therefore conducted a 7T multimodal imaging study to chara...
