Journal Article
In vivo electron paramagnetic resonance imaging of tumor heterogeneity and oxygenation in a murine model.
Periannan Kuppusamy,Mobae Afeworki,Ravi A. Shankar,Deborah Coffin,Murali C. Krishna,Stephen M. Hahn,James B. Mitchell,Jay L. Zweier +7 more
TL;DR: This study demonstrates that electron paramagnetic resonance imaging can perform noninvasive anatomical as well as functional imaging and provide in vivo physiological information regarding cellular metabolism in tumor and normal tissues.
Journal ArticleDOI
In vivo imaging of a stable paramagnetic probe by pulsed-radiofrequency electron paramagnetic resonance spectroscopy.
Ramachandran Murugesan,John A. Cook,Nallathamby Devasahayam,Mobae Afeworki,Sankaran Subramanian,Rolf Tschudin,Janhenrik A. Larsen,James Mitchell,Angelo Russo,Murali Krishna +9 more
TL;DR: Results from this study suggest a potential use for pulsed RF EPR imaging (EPRI) for three‐dimensional spatial and spectral‐spatial imaging applications, and may find use in in vivo studies to minimize motional artifacts from cardiac and lung motion that cause significant problems in frequency‐domain spectral acquisition.
Journal ArticleDOI
Parallel coil resonators for time-domain radiofrequency electron paramagnetic resonance imaging of biological objects.
Nallathamby Devasahayam,S. Subramanian,Ramachandran Murugesan,John A. Cook,Mobae Afeworki,Rolf Tschudin,James B. Mitchell,Murali C. Krishna +7 more
TL;DR: Imaging studies with phantom objects containing a narrow-line spin probe as well as in vivo objects administered with thespin probe show the suitability of these resonators for valid reproduction of the spin probe distribution in three dimensions.
Journal ArticleDOI
Three-dimensional whole body imaging of spin probes in mice by time-domain radiofrequency electron paramagnetic resonance.
Mobae Afeworki,Gooitzen M. van Dam,Nallathamby Devasahayam,Ramachandran Murugesan,John A. Cook,Deborah Coffin,Jan H. A.-Larsen,James B. Mitchell,Sankaran Subramanian,Murali C. Krishna +9 more
TL;DR: The results from these studies suggest that, with the use of stable paramagnetic spin probes and time‐domain RF EPR, it is possible to perform in vivo imaging on animals and also obtain important spatially resolved physiologic information.
Journal ArticleDOI
A broadband pulsed radio frequency electron paramagnetic resonance spectrometer for biological applications
Ramachandran Murugesan,Mobae Afeworki,John A. Cook,Nallathamby Devasahayam,Rolf Tschudin,James Mitchell,Sankaran Subramanian,Murali Krishna +7 more
TL;DR: In this paper, a time-domain radio frequency (rf) electron paramagnetic resonance (EPR) spectrometer/imager capable of detecting and imaging free radicals in biological objects is described.
