Temperature and concentration calibration of aqueous polyvinylpyrrolidone (PVP) solutions for isotropic diffusion MRI phantoms
To use the "apparent diffusion coefficient" (Dapp) as a quantitative imaging parameter, well-suited test fluids are essential. In this study, the previously proposed aqueous solutions of polyvinylpyrrolidone (PVP) were examined and temperature calibrations were obtained. For example, at a temperature of 20°C, Dapp ranged from 1.594 (95% CI: 1.593, 1.595) μm2/ms to 0.3326 (95% CI: 0. 3304, 0.334...
متن کاملPolyvinylpyrrolidone (PVP) water solutions as isotropic phantoms for diffusion MRI studies
Introduction As Diffusion Tensor MRI (DTI) and other diffusion MRI applications are becoming more widespread clinically, the need to develop a phantom for diffusion MRI calibration and quality control is essential. Standard MRI phantoms are often suboptimal as diffusion phantoms because they have diffusivities that are too large to be representative of those found in biological tissues. Tofts e...
متن کاملComponent dynamics in polyvinylpyrrolidone concentrated aqueous solutions.
(2)H-nuclear magnetic resonance (NMR) and neutron scattering (NS) on isotopically labelled samples have been combined to investigate the structure and dynamics of polyvinylpyrrolidone (PVP) aqueous solutions (4 water molecules/monomeric unit). Neutron diffraction evidences the nanosegregation of polymer main-chains and water molecules leading to the presence of water clusters. NMR reveals the s...
متن کاملTemperature and concentration dependence of diffusion coefficient in dilute solutions*
Temperature and molecular weight dependence of k o in D(C)=D(O)[1 +CkD], where D(C) is the diffusion coefficient for the density fluctuations in a dilute polymer solution, is investigated by first expressing D(C) as a function of the static structure factor S(q,C) within the framework of the Kirkwood-Riseman theory. The continuous transition of k D from negative values under theta conditions to...
متن کاملManufacturing and acoustical characterization of electrospun PolyVinylPyrrolidone (PVP) Blankets
In this work, new light soundproofing fibrous materials were obtained through electrospinning technique. The sound absorbers were obtained in the form of blankets of thin disks of 10 cm diameter, characterized by fibres with a diameter in order of 2 μm. Different activities involved for acoustical characterization of specimens, in particular to the evaluation of the sound absorption coefficient...
