I am an Associate Professor in the Department of Radiology at the University of Minnesota. After receiving B.S. and B.A. degrees in Chemistry and Criminology & Law at the University of Florida, in 1997 I began my career in MRI physics and functional neuroimaging research by joining the lab of Drs. Richard Briggs and Bruce Crosson at the University of Florida as an undergraduate research assistant. I joined the Center for Magnetic Resonance Research (CMRR) at the University of Minnesota in 1998. Working with Drs. Xiaoping Hu and Kâmil Uğurbil, I received my Ph.D. in Biomedical Sciences and Medical Physics from the University of Minnesota in 2003.

My research focuses on developing and integrating software and hardware for improving MRI image quality, resolution, and acquisition speed. I have been especially interested in the use of ultra-high magnetic fields to achieve these goals, having started my career working on one of the first 3 Tesla whole-body human scanners at the University of Florida in 1997, then moving to the University of Minnesota where I have had the opportunity to work on the most powerful whole-body human MRI scanners in the world, such as the first 7 Tesla (installed at CMRR in 1999) and the first and only 10.5 Tesla (installed at CMRR in 2014).

For the past 26 years, researchers in the Garwood laboratory have had a focus on developing cutting-edge MRI and MR spectroscopy techniques and on exploiting them in studies of tissue function, metabolism, and microstructure. An emphasis has been on identifying and validating quantitative metrics to assess normal and disease states non-invasively with imaging, and on applying them to learn about metabolism, hemodynamics, and tissue micro-environment. On the technical side, the Garwood group has recently made a significant advancement in the way MRI is performed - a technique called SWIFT. SWIFT exploits time-shared RF excitation and acquisition to preserve signals from water molecules possessing extremely short transverse relaxation times, T2 and T2*. With SWIFT, broadband frequency-swept excitation, together with extremely short acquisition delay, make it possible to also preserve frequency-shifted signals in the vicinity of magnetic objects. For example, magnetically-labeled nanoparticles (e.g., SPIOs), which cause signal voids in conventional MR images, give rise to positive contrast (bright spots) in SWIFT images, thus improving the capability to track and quantify targeted contrast agents and molecular therapies, as well as magnetically-labeled cells. Finally, the Garwood group has a focus on the physics of nuclear magnetic resonance relaxation, in an effort to improve the sensitivity and specificity of MRI for disease characterization, diagnosis, and treatment monitoring. In particular, we are developing ways to "tune" MRI's specificity to certain dynamic processes in tissues (e.g., assessing the tumbling times and exchange rates of different pools of tissue water) and we are investigating their utility as quantitative markers of neurodegeneration and cancer aggressiveness, and as early indicators of response to treatments. These methods are currently in pre-clinical and clinical trials (lung, breast, and brain cancers; Parkinson's disease, and multiple sclerosis) in collaboration with other faculty in the University of Minnesota and elsewhere.

Research Summary

To apply theoretical formalisms to describe the magnetic resonance phenomenon; in particular, the interaction between nuclear spins and a radiofrequency field having a variable amplitude and frequency in time.
To exploit the unique properties of these frequency-modulated RF techniques to enhance sensitivity and data quality in MRI and MRS.
To expose molecular properties of cancers using MRI and MRS, and to use these for making diagnoses and for evaluating and guiding cancer treatments, all non-invasively.

My interests and career focus is hardware development and its implementation in support of biomedical applications. After obtaining my Ph.D., I worked for nine years at Intermagnetics General Corporation (acquired by Philips in 2006) as scientist developing radio frequency (RF) hardware and applications for MRI animal systems. In 1990 I joined the University of Minnesota as an Assistant Professor of Radiology to advance MRI applications. During my tenure at the U of MN I formed the Center for Interdisciplinary Applications in Magnetic Resonance (CIA-MR) that housed a 1.5 T/680mm MRI system, a 5.0 T/400mm MRI system and a 17 T/50 mm vertical bore levitation magnet. These systems were instrumental in laying the foundation for developing the concept of a hybrid MR-PET scanner, integrating a 6 MeV LINAC into a 1.5 MRI scanner and developing magnetic levitation as a ground-based research tool to simulate microgravity. The CIAMR supported MR activities for several investigators that studied 31P NMR of hemorrhagic shock, MR imaging and spectroscopy of pancreas and islet viability, bioreactor development and function and cryopreservation. On August 1, 2007, collapse of the I35W bridge in Minneapolis forced the CIAMR to cease operations because it was within 50 feet of the bridge. The lab was relocated in August 2008 to a 5,800 sq. ft facility in Minnetonka, MN, about 18 miles from campus.

Research Summary

My present research focus is to develop magnetic levitation as a ground-based tool to study the effects of gravitation on biological systems. In November 2010, the 17 T levitation magnet moved from the CIAMR Minnetonka lab to the newly expanded 60,000 sq. ft. CMRR facility for better access to university resources in support of levitation studies. Ancillary projects I am actively pursuing include development of an implantable NMR spectrometer on a chip (Prof. Harjani, UMN-Minneapolis), Real-time 3D three-dimension tracking of organ deformations in minimum invasive surgery (Prof. Tewfik, UT-Austin) and contract research to support companies developing MR-conditional devices.

Dr. Harel is a Professor in the departments of Radiology and Neurosurgery, at the University of Minnesota. After receiving his B.Sc. in biology from Tel Aviv University, Israel, Dr. Harel moved to the University of Toronto, Canada, where he received his MSc (1996) and PhD (2000) in Physiology and Neuroscience for mapping auditory areas using optical imaging technique. For his post doctoral training, Dr. Harel moved to the Center for Magnetic Resonance Research (CMRR), University of Minnesota where his research focused on the development of methods for high-resolution MRI and functional MRI (fMRI) applications using high magnetic fields (7T & 9.4T). In particular, Dr. Harel developed fMRI capabilities for mapping columnar and laminar organization in cerebral cortex both in human and animal models. In 2002, Dr. Harel moved to the University of Pittsburgh as a research associate and soon after returned to Minnesota and joined CMRR as a faculty member.Dr. Harel's current research focuses on the development and integration of 7T and high field neuroimaging data into deep brain stimulation (DBS) surgical navigation in particular and brain surgery in general.

Research Summary

My group focuses on using Magnetic Resonance Spectroscopy (MRS) to understand brain function at the biochemical and cellular level, and to identify new biomarkers of brain disorders. Current research topics include:
To understand how neurons and astrocytes cooperate metabolically to support neurotransmission. For this purpose, we perform tracer studies using 13C-labeled substrates and 13C MRS, which allows us to measure metabolic rates non-invasively in the brain in both neurons and astrocytes.
To develop new metabolic models to analyze 13C MRS data, particularly two-compartment neuronal-glial models to measure the "glutamate-glutamine cycle". This would provide a non-invasive measurement of glutamatergic neurotransmission.
To explore the potential of hyperpolarized 13C for the study of brain metabolism and for the detection of tumors in brain and other tissues.
To develop new methodologies for 1H MRS and 1H MRSI at very high-field for the measurement of metabolite concentrations ("neurochemical profile") with improved spatial and temporal resolution.
