Light beating spectroscopy measurements of microemulsion diffusion coefficient

Reproducibility of Apparent Diffusion Coefficient Measurements in Malignant Breast Masses

This study aimed to evaluate the reproducibility of apparent diffusion coefficient (ADC) measurements in malignant breast masses, and to determine the influence of mammographic parenchymal density on this reproducibility. Sixty-six patients with magnetic resonance findings of the mass were included. Two breast radiologists measured the ADC of the malignant breast mass and the same area on the c...

Single-image diffusion coefficient measurements of proteins in free solution.

Diffusion coefficient measurements are important for many biological and material investigations, such as studies of particle dynamics and kinetics, and size determinations. Among current measurement methods, single particle tracking (SPT) offers the unique ability to simultaneously obtain location and diffusion information about a molecule while using only femtomoles of sample. However, the te...

Particle Size Measurements Using Diffusion Broadening Spectroscopy

Investigating Diffusion Coefficient Using Dynamic Light Scattering Technique

In this work, the Z-average, effective, apparent diffusion coefficients and their poly-dispersity indexes were investigated for dilute poly-disperse homogeneous spherical particles in dispersion where the Rayleigh-Gans-Debye approximation is valid. The results reveal that the values of the apparent and effective diffusion coefficients at a scattering angle investigated are consistent and the di...

Optimization of spectroscopy-based diffusion measurements of intramyocellular lipids

Introduction: H MR spectra of skeletal muscle feature two distinct contributions from lipids, intramyocellular lipids (IMCL) stored as lipid droplets inside the cytoplasm of the muscle cells and extramyocellular lipids (EMCL) located in fascia along the muscle fibers [1]. It has been established that IMCL play an important role in energy metabolism and are linked to insulin resistance [1]. The ...
