Human Magnetic Resonance Center

Human Magnetic Resonance Center

Announcements

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: Resting state and task-based functional brain imaging (fMRI) are used to investigate neurotypical brain connectivity and regional function across the lifespan, and to understand brain dysfunction and neuroplasticity.

Spectroscopy: Magnetic resonance spectroscopy is used to measure the molecular composition of a tissue or muscle.

Structural 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.

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.

Additional Equipment

  • The hMRC is equipped with 3 head coils (20, 32, and 64 channel), and a full array of body, foot/ankle, knee, and breast coils, and a docking exam table.
  • A variety of MR compatible peripheral equipment is available, such as a 32” high resolution BOLD screen, a 128-channel EEG system, an eyetracking system, an active noise canceling microphone/headphone system, a system for MR elastography, an ergometer, and an array of button box, grip force, and joystick devices for acquiring experimental responses.
  • The hMRC has a complete mock scanner system, including participant interfaces, and is particularly well suited for training participants to stay still in the scanner.
  • Double tuned 1H-31P and 1H-13C surface coils.

Services

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.

Functional Neuroimaging
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.

Spectroscopy
Magnetic resonance spectroscopy (MRS) is used to measure the molecular composition of a tissue or muscle.

Structural imaging
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:

  • Feasibility scan: To evaluate your study using our facility and protocols, we may provide you courtesy scans once your feasibility scan request is approved by our co-directors. It is not mandatory to have an approved IRB protocol, but it is recommended to have an IRB protocol for human subject scans.
  • Pilot scan: To collect preliminary data for an extramural grant, you may also apply for pilot funding to acquire pilot data at a reduced scan fee. You need to have an approved IRB protocol to acquire pilot data.
  • Regular scan: You will be asked to pay for the full scan fee ($550/hr) and to provide an approved IRB protocol.
  • Other scans: We also provide courtesy scans for student training and education, development and testing of equipment and scan protocols, and other public needs. These scans will be required to be approved by our co-directors.

Please apply to scanning of all types using the Pilot/Feasibility form.

  • The scan schedule is managed using a google calendar at hmrc@umass.edu.
  • To schedule your MR scan, please review the "3T Scheduling Procedure" document before sending an email to your MR physicist or to hmrc@umass.edu.

hMRC Pilot Grant Program-Round 2 (PGP) is designed to assist faculty who utilize MR methods in their research to obtain sponsored funding, while supporting the long-term success of the hMRC.

Jacquie Kurland, PhD
Dr. Kurland studies functional reorganization in post-stroke aphasia. She uses structural and functional task-based and resting state MRI to examine treatment-induced neuroplasticity and language recovery in aphasic stroke survivors and the influence of practice on age-matched and younger neurotypical controls.

Kwan-Jin Jung, PhD
Dr. Jung is an engineer in Electronics and specializes in MR physics and signal processing for functional MRI, diffusion imaging and MR instrumentation.

Rajakumar Nagarajan, PhD
Rajakumar Nagarajan is the MR Physicist working at Human Magnetic Resonance Center (hMRC), UMass, Amherst. He has strong MR Physics background and expertise in MR spectroscopy, including multinuclear spectroscopy, time series analysis, and spectroscopic or chemical shift imaging. He provides technical assistance with magnetic resonance (MR) protocol development and evaluation, data collection, advanced processing of data, and oversight of MR technician. Rajakumar trains and support faculty or trainees about MR safety, data acquisition and post-processing. He provides timely support to investigators for grant funding and also monitors new developments and improvements in technology to keep core competitive and state-of-the-art.  Relevant publications:  PubMed | Google Scholar

Please use the following IRB approved forms and templates when you submit your IRB protocol for all MRI/MRS human subjects studies:

hMRC is dedicated to research of human MR imaging and spectroscopy. We do not provide any clinical diagnosis.

If you have any question, please contact our staff or send an email to hmrc@umass.edu.


Scan Preparation

The MRI scan uses a strong magnetic field but it does not use radiation like in computer tomography or positron emission tomography. Therefore, MRI is non-invasive, but you need to follow a few safety precautions:

  • Wear comfortable clothing, preferablly made of cotton and loose fitting.
  • If you tend to get cold, bring a cotton sweatshirt - with no 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 can qualify for the MRI scan using this IRB approved hMRC Safety Questionnaire.

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*.
