Mapping complex tissue architecture with diffusion spectrum magnetic resonance imaging

Magnetic Resonance in Medicine, 2005
Methods are presented to map complex fiber architectures in tissues by imaging the 3D spectra of tissue water diffusion with MR. First, theoretical considerations show why and under what conditions diffusion contrast is positive.

Common neuroanatomical differential factors underlying heterogeneous gray matter volume variations in five common psychiatric disorders

Communications Biology
Multifaceted evidence has shown that psychiatric disorders share common neurobiological mechanisms. However, the tremendous inter-individual heterogeneity among patients with psychiatric disorders limits trans-diagnostic studies with case-control designs,

Hypertrophy cardiomyopathy: A case of infantile-onset Pompe disease in cardiac magnetic resonance findings

Heliyon, 2023
There are two clinical types of Pompe disease: infantile-onset and late-onset, while the former is much more severe. We reported a typical case of Pompe disease in a 9-month infant who presenting with repeated pneumonia, growth retardation and ...
