Autor: Michael Garwood, Ryan Chamberlain, Curtis A. Corum, John C. Bischof, Michael L. Etheridge, Jinjin Zhang, Djaudat S. Idiyatullin

Publikováno v: Magnetic Resonance in Medicine. 71:1982-1988

Purpose Iron-oxide nanoparticles (IONPs) have proven utility as contrast agents in many MRI applications. Previous quantitative IONP mapping has been performed using mainly T2* mapping methods. However, in applications requiring high IONP concentrati

Short echo-time 3D radial gradient-echo MRI using concurrent dephasing and excitation

Autor: Steen Moeller, Michael Garwood, Jang-Yeon Park, Ute Goerke, Ryan Chamberlain, Jutta M. Ellermann, Edward J. Auerbach

Publikováno v: Magnetic Resonance in Medicine. 67:428-436

Ultrashort echo-time imaging and sweep imaging with Fourier transformation are powerful techniques developed for imaging ultrashort T(2) species. However, it can be challenging to implement them on standard clinical MRI systems due to demanding hardw

Normal spectrum of pulmonary parametric response map to differentiate lung collapsibility: distribution of densitometric classifications in healthy adult volunteers

Autor: Mariaelena Occhipinti, Mario Silva, Stefan F. Nemec, Ryan Chamberlain, Valerie Dufresne, Benedikt H. Heidinger, Alexander A. Bankier

Publikováno v: European radiology. 26(9)

Pulmonary parametric response map (PRM) was proposed for quantitative densitometric phenotypization of chronic obstructive pulmonary disease. However, little is known about this technique in healthy subjects. The purpose of this study was to describe
