Cortical organoid diffusion MRI reveals protocol-associated spatial reproducibility and increasing apparent diffusivity with diffusion time

This study uses cortical organoids to examine diffusion MRI reproducibility and apparent diffusivity changes with diffusion time, finding increased apparent mean diffusivity in most tissue voxels.

OCTOPUS: A versatile open-source tool creating realistic numericalbrain cells

OCTOPUS generates realistic digital brain cells with complex geometries to improve dMRI signal modeling and validate biophysical models.

Regional BOLD variability reflects microstructural maturation and neuronal ensheathment in the preterm infant cortex

The paper examines how BOLD variability in preterm infants relates to cortical microstructure and gene expression, finding increased variability in specific regions with decreased diffusivity and upregulated gliogenesis genes.

Defacing biases visual quality assessments of structural MRI

This study assesses how defacing structural MRI images affects quality assessments by humans and automated tools, finding significant human bias and minimal impact on MRIQC metrics.

Do you see what I see? Diffusion imaging protocol heterogeneity biases ischemic core volume, location, and clinical associations in acute stroke

This paper shows that differences in diffusion imaging protocols affect ADC maps, leading to variations in infarct core volume, location, and clinical score associations in acute stroke.
