Biophysical Mechanisms of Microscopic Diffusional Kurtosis in diffusion MRI

2026-03-19

Abstract excerpt

<title>Abstract</title> <p>The Standard Model of diffusion MRI represents diffusion in tissue using multiple Gaussian components, an approximation that misses key non-Gaussian effects from intra-compartmental structural disorder and/or intercompartmental water exchange. These biophysical mechanisms are conflated in conventional measures such as diffusional kurtosis, and exchange is commonly described using the Kä...
