dicompare schema: Protocols for DWI analysis (v1.1)

Jelle Veraart, Santiago Coelho

**Overview:** Diffusion-weighted MRI enable the quantification of brain microstructure and structural connectivity in the living human brain using various modeling and analysis approaches. Each of such modeling and analysis approaches have specific requirements in terms of b-values, diffusion-weighting gradients, and others. Here …

Disentangling Pontine Fiber Geometry and Microstructure in ARSACS Using Advanced MRI

Ilana R. Leppert, Aziz Benbachir, Jennifer SW Campbell, Santiago Coelho et autres

1 Abstract Background Autosomal recessive spastic ataxia of Charlevoix-Saguenay (ARSACS) is a genetic disease characterized by spasticity and ataxia which reflects involvement of the corticospinal tracts (CST) and cerebellum. The primary involvement of the middle cerebellar peduncles (MCP) and transverse pontine fibers …

Geometry of the cumulant series in diffusion MRI

Santiago Coelho, Jenny Chen, Filip Szczepankiewicz, Els Fieremans et autres

Water diffusion gives rise to micron-scale sensitivity of diffusion MRI (dMRI) to cellular-level tissue structure. Precision medicine and quantitative imaging depend on uncovering the information content of dMRI and establishing its parsimonious hardware-independent fingerprint. Based on the rotational SO(3) symmetry, we study …

What If Each Voxel Were Measured With a Different Diffusion Protocol?

Santiago Coelho, Gregory Lemberskiy, Ante Zhu, Hong‐Hsi Lee et autres

Expansion of diffusion MRI (dMRI) both into the realm of strong gradients, and into accessible imaging with portable low-field devices, brings about the challenge of gradient nonlinearities. Spatial variations of the diffusion gradients make diffusion weightings and directions non-uniform across the field …

Normal appearing white matter and disability in multiple sclerosis

В. Н. Степанов, Santiago Coelho, Benjamin Ades‐Aron, Jenny Chen et autres

ABSTRACT Background and Objectives Multiple sclerosis (MS) is characterized by lesions and atrophy on conventional MRI, yet these often fail to explain disability. Diffusion MRI (dMRI) detects microstructural injury with diffusion tensor (DTI) and kurtosis imaging (DKI) offering sensitivity, and Standard Model …

Linking Symptom Phenotypes to Patterns of White Matter Injury in Mild Traumatic Brain Injury: A Latent Class Analysis

Sohae Chung, Seon-Hi Shin, Alaleh Alivar, Jed N. McGiffin et autres

BACKGROUND AND PURPOSE: Mild traumatic brain injury (MTBI) is a common public health concern with potential long-term consequences, yet its underlying pathophysiology remains poorly understood. Clinical heterogeneity of individuals having diverse extent and array of symptoms has impeded the identification of reliable …

Microscopic kurtosis tensor invariants and DDE 4-fold angular modulation in human brain diffusion MRI

Santiago Coelho, Els Fieremans, Dmitry S. Novikov

Motivation: dMRI signal at moderate diffusion-weightings $$$\sim\,b^2$$$ has contributions from intrinsic (microstructural) kurtosis, and from heterogeneity of compartments. Goal(s): To separate all kurtosis sources and provide a complete set of tensor invariants for a most general distribution of non-Gaussian compartments. Approach: We …

Microstructure and muscle strength in older adults: a time-dependent diffusion study

Valentina Mazzoli, Gregory Lemberskiy, Thorsten Feiweier, Gregor Koerzdoerfer et autres

Motivation: Treatments exist to help prevent the development of sarcopenia and muscle atrophy in older adults, but the detection of early signs of atrophy is challenging. DTI can detect features of muscle atrophy associated with decrease force production, but it has low …
