Progressive White Matter Changes in Mitochondrial Disease: A Quantitative MRI Study
ABSTRACT Primary mitochondrial diseases frequently affect the central nervous system, yet the extent, distribution and progression of white matter hyperintensities (WMHs) remain insufficiently characterised, particularly in terms of quantitative volumetrics and longitudinal progression.

ABSTRACT Purpose To propose a signal acquisition and modeling framework for multi‐component tissue quantification that encompasses transmit field inhomogeneity, multi‐component relaxation and magnetization transfer (MT) effects. Theory and Methods By applying off‐resonance irradiation between excitation and acquisition within an RF‐spoiled gradient ...

ABSTRACT Purpose To investigate how the relaxation rates (R1, R2) and asymmetry indices (AI), derived from phase‐cycled balanced steady‐state free precession (pc‐bSSFP) data, depend on the orientation of white matter (WM) fiber tracts at different field strengths.

Exploring the Role of Vascular Factors and Tissue Properties in Pulsatile Brain Deformation
This study combined strain tensor imaging (STI), intrinsic magnetic resonance elastography (iMRE), and atlas‐based regional metrics to explore physiological drivers of cardiac‐induced brain strain. Volumetric strain was mainly associated with vascular factors such as cerebral blood volume and pulse pressure, whereas octahedral shear strain correlated ...

Background Bipolar I disorder (BD) is associated with reduced white matter microstructural integrity in the uncinate fasciculus (UF), a primary fiber tract connecting frontolimbic systems. Although familial history for BD, attention‐deficit/hyperactivity disorder (ADHD), and psychostimulants are important risk factors implicated in BD pathoetiology ...

ABSTRACT Background Daily activities require the simultaneous execution of cognitive and motor tasks. Type 2 diabetes mellitus (T2DM) is associated with functional impairments that may compromise dual‐task performance, leading to increased dual‐task interference.
