Map** tissue microstructure with MRI holds great promise as a noninvasive window into
tissue organization at the cellular level. Having originated within the realm of diffusion NMR …

We review, systematize and discuss models of diffusion in neuronal tissue, by putting them
into an overarching physical context of coarse‐graining over an increasing diffusion length …

A magnetic resonance imaging method is presented for quantifying the degree to which
water diffusion in biologic tissues is non‐Gaussian. Since tissue structure is responsible for …

Chronic obstructive pulmonary disease (COPD) is the third leading cause of death
worldwide. COPD, however, is a heterogeneous collection of diseases with differing causes …

The charge of this Joint ATS/ERS Task Force was to critically review the state-of-the-art
stereological methods in lung morphometry, provide practical guidelines for use of these …

By permitting direct visualization of the airspaces of the lung, magnetic resonance imaging
(MRI) using hyperpolarized gases provides unique strategies for evaluating pulmonary …

The small airways are defined as those less than 2 mm in diameter. They are a major site of
pathology in many lung diseases, not least chronic obstructive pulmonary disease (COPD) …

Restricted diffusion is a common feature of many physicochemical, biological, and industrial
processes. Nuclear magnetic resonance techniques are often used to survey the atomic or …

Rationale: The current hypothesis that human pulmonary alveolarization is complete by 3
years is contradicted by new evidence of alveolarization throughout adolescence in …

Diffusion-weighted imaging (DWI) provides a noninvasive tool to probe tissue
microstructure. We propose a simplified model of neural cytoarchitecture intended to capture …
