Human Magnetic Resonance Center
Core Facilities Seminar
Gwenael Layec, Assistant Professor, Kinesiology Department and IALS–Investigation of Muscle Function by MR Spectroscopy/Imaging
Located on the 2nd floor in the Life Science Laboratories the Human Magnetic Resonance Center (hMRC) provides state-of-the-art, non-invasive neuroimaging, whole body imaging, and spectroscopy technologies for academic and industry-based research in central and western Massachusetts. This is the only research-dedicated 3T MRI/MRS system in western Massachusetts. This system is ideal for investigating questions regarding normal and abnormal changes in human brain and whole body structure and function across the lifespan.
The hMRC houses a 3 Tesla Siemens Skyra scanner for basic and translational research including:
Functional Neuroimaging: Noninvasive imaging that measures brain activity and function during resting state and task-based imaging (fMRI) by detecting dynamic physiological processes in real time associated with blood flow and the blood oxygen levels in response to neural activation and consumption, this is referred to as BOLD or Blood Oxygen Level Dependent Imaging. This is used to investigate neurotypical brain connectivity and regional function across the lifespan and to understand brain dysfunction and neuroplasticity.
Spectroscopy: Magnetic resonance spectroscopy (MRS) is a noninvasive data collection technique that is ideal for measuring biochemical content and metabolism of tissues in the body. This method allows us to gather metabolic information, which is unique and independent, but complementary to the anatomic information obtained with other magnetic resonance imaging (MRI) techniques in various pathology. MRS is able to display data in various ways, including chemical composition and measurement of the spatial distribution of metabolite concentrations.
Structural brain imaging: Static imaging of the white and gray matter and CSF of the brain, as well as bone and tissue, are used to examine typical structural morphology and connectivity, as well as atypical structure, neuroplasticity, and neurodegeneration.
Musculoskeletal & Whole Body MRI: Demonstrates various aspects of muscle, organ, bone, joint, soft tissue and nerve structure and function. High resolution images can be generated in which the following details can be demonstrated: fat, muscle, tendons, ligaments, and fluid as well as vasculature and nerve systems. These can be used to quantify various data such as fat quantification, edema, pathology and structural damage or degeneration.
Siemens 3T Skyra Scanner
Siemens 3T (123 MHz) Skyra is a 70-cm bore MRI/MRS scanner for acquisition of BOLD, Diffusion, and MR spectroscopy data. The scanner uses state-of-the-art technology for fast and efficient collection of:
- structural neuroimaging (white and gray matter and CSF morphology and diffusion tractography),
- functional neuroimaging (resting state and task-based fMRI),
- multi-nuclear spectroscopy (1H, 31P and 13C)
- MR elastography
- structural imaging of bone and tissue,
The Skyra provides a wide bore and short length, making it ideal for scanning certain populations, e.g., children and obese persons, who may otherwise feel claustrophobic in a typical 60mm bore.

As a core facility, the Human Magnetic Resonance Center is a resource for basic and translational MRI and MRS research both from investigators on-campus and off.
UMass Amherst neuroscientists use state-of-the-art structural and functional brain imaging techniques. Functional MRI (fMRI) is used to determine areas of the brain that contribute to performance of specific tasks. High-resolution structural images can be useful for identifying changes in the brain such as those associated with development, aging, or disease.
Magnetic resonance spectroscopy (MRS) is used to measure the molecular composition of a tissue or muscle.
In addition to structural brain imaging, static imaging of bone and tissue is used to identify skeletal, muscular, or differences across populations or individuals.
Staff physicists are available to assist new users with protocol development, implementation, and analysis. Services include:
- Consultation and development of MRI and MRS protocols
- Consultation and development of MR-compatible stimuli and participant interface
- Analysis of pilot data and training and assistance with subsequent studies
- Assistance with MR aspects of grant proposals.
We provide four different levels of scan services to accommodate your studies:

The MRI scan uses a strong magnetic field but it does not use ionizing radiation like in computer tomography or positron emission tomography. Therefore, MRI is non-invasive, but you will need to follow a few safety precautions and complete a screening form prior to scanning:
- Wear comfortable clothing, preferably made of cotton and loose fitting.
- If you tend to get cold, bring a cotton sweatshirt with no hood or zipper.
- Remove any metal items from you pockets (e.g., pens, keys, loose change, etc.) and from your body (e.g., watches, jewelry, body piercings, etc.).
- For women it is recommended to wear a sports bra (i.e., no metallic clasp).
- If you wear eyeglasses, and you will be a participant in fMRI research involving visual stimuli, bring your eyeglasses prescription data.
You can check whether you would qualify for an MRI scan by reviewing the hMRC Safety Questionnaire. If you have any questions regarding the form or scan, please contact your researcher or hMRC staff.
It will be helpful if you fill out the form and consult the researcher administering the experiment with any questions you may have–*prior to the day of the experiment*.
