Hyperpolarized Long-T1 Silicon Nanoparticles for Magnetic Resonance Imaging
J. W. Aptekar, M. C. Cassidy, A. C. Johnson +14
Silicon nanoparticles are experimentally investigated as a potential hyperpolarized, targetable MRI imaging agent. Nuclear T_1 times at room temperature for a variety of Si nanopar…
Posture-Dependent Human 3He Lung Imaging in an Open Access MRI System: Initial Results
L. L. Tsai, R. W. Mair, C. -H. Li +3
The human lung and its functions are extremely sensitive to orientation and posture, and debate continues as to the role of gravity and the surrounding anatomy in determining lung…
Noninvasive measurements of gas exchange in a three-dimensional fluidized bed using hyperpolarized 129Xe NMR
Tina Pavlin, Ruopeng Wang, Ryan McGorty +5
We present a novel NMR technique that provides a non-invasive, direct measurement of gas exchange in a three-dimensional gas-fluidized bed of solid particles. The NMR spectrum of h…
Using NMR to Validate First-Principles Granular Flow Equations
D. Candela, C. Huan, K. Facto +3
Nuclear magnetic resonance (NMR) experiments are described for two granular-flow systems, the vibrofluidized bed and the gas-fluidized bed. Using pulsed field gradient, magnetic re…
Xenon NMR Measurements of Permeability and Tortuosity in Reservoir Rocks
R. Wang, T. Pavlin, M. S. Rosen +3
In this work we present measurements of permeability, effective porosity and tortuosity on a variety of rock samples using NMR/MRI of thermal and laser-polarized gas. Permeability…
Study of Gas-Fluidization Dynamics with Laser-Polarized 129Xe
R. Wang, M. S. Rosen, D. Candela +2
We report initial NMR studies of gas dynamics in a particle bed fluidized by laser-polarized xenon (129Xe) gas. We have made preliminary measurements of two important characteristi…
