Purpose Diffusion and lung morphometry imaging using hyperpolarized gases are promising tools to quantify pulmonary microstructure noninvasively in humans and in animal models. These techniques assume the motion encoded is exclusively diffusive gas d

Autor: Randy Giaquinto, Zackary I. Cleveland, Matthew S. Freeman, Scott H. Robertson, Ronald G. Pratt, Peter Niedbalski, Wolfgang Loew, Matthew M. Willmering, Jason C. Woods, Christopher Ireland, Charles L. Dumoulin

Publikováno v: Magn Reson Med

PURPOSE: Hyperpolarized (HP) media enable biomedical imaging applications that cannot be achieved with conventional MRI contrast agents. Unfortunately, quantifying HP images is challenging, because relaxation and radio-frequency pulsing generate spat

Improved preclinical hyperpolarized 129 Xe ventilation imaging with constant flip angle 3D radial golden means acquisition and keyhole reconstruction

Autor: Zackary I. Cleveland, Peter Niedbalski

Publikováno v: NMR in Biomedicine. 34

Hyperpolarized (HP) 129 Xe MRI is increasingly used to noninvasively probe regional lung structure and function in the preclinical setting. As in human imaging, the primary barrier to quantitative imaging with HP gases is nonequilibrium magnetization

Publikováno v: J Magn Reson

Yttrium (III) complexes are interesting due to the similarity of their chemistry with gadolinium complexes that are used as contrast agents in nuclear magnetic resonance (NMR) spectroscopy or imaging (MRI). While most of the paramagnetic Gd(3+)-based

Publikováno v: J Appl Physiol (1985)

Magnetic resonance (MR) imaging and spectroscopy using dissolved hyperpolarized (HP) (129)Xe have expanded the ability to probe lung function regionally and noninvasively. In particular, HP (129)Xe imaging has been used to quantify impaired gas uptak
