Powerful new MRI keeps Queensland scientists at forefront of brain science

25 Mar 2007

Neuroscientists at the Queensland Brain Institute (QBI) are astounded at the detail available to them in brain images being generated by UQ's new Magnetic Resonance Imaging (MRI) spectrometer.

QBI Director Professor Perry Bartlett said the new MRI represented a quantum advance in brain-imaging technology.

“This is an extremely exciting development. We've learned a lot about how we think the brain works, but we've never been able to look at it in real time,” Professor Bartlett said.

“This imaging capability will allow us for the first time to rapidly identify and really interrogate the mechanisms controlling brain function and apply these discoveries to the treatment of disease.

“And it puts Queensland right in front of the pack … leading the world in discovery in this area.”

Professor Bartlett said QBI scientists were currently using the technology to look at molecules they believed would help with the regrowth of damaged nerve cells following trauma such as spinal cord injury.

“If this proves successful in animal models we could conceivably go to trials within the next 18 months to two years,” he said.

“Imaging technology such as this is vital if we are to address the overwhelming incidence of neurological disorders on the community.”

Located at The University of Queensland's Centre for Magnetic Resonance (CMR) and purchased with the assistance of Queensland Government Smart State Funding, the new 16.4T MRI wide-bore spectrometer is one of fewer than six such machines anywhere in the world.

CMR Acting Director Professor Ian Brereton said the technology enabled scientists to obtain exquisitely detailed images of intact biological specimens, at spatial resolution approaching the cellular level.

“This instrumentation is a key addition to the imaging capacity being built at this university to support major initiatives in molecular imaging, cognitive and anatomical neuroscience, biomarker development and nanotechnology,” Professor Brereton said.

“As part of the Queensland NMR Network, these world-class facilities will provide all researchers throughout Queensland and the region with access to state-of-the-art imaging technology and expertise.”

Among the many benefits expected to flow from long-term application of this technology include the:

  • Capacity for scientists to study brain function at the cellular level, allowing researchers to image at high resolution and better understand how memory and learning are regulated;
  • Development of improved diagnostic procedures and treatments for sufferers of neurological disorders ranging from dementia to Motor Neuron Disease;
  • Opportunity to study tissue from stroke and other neurological disease models;
  • Development of new imaging protocols and markers to study cell function and movement; and
  • Capacity to conduct clinical trials in the animal model, a vital step in the development of safe therapeutic treatments for humans.

Leading neuroscientists from Australia, Korea and the United States will attend an advanced-imaging symposium in Brisbane on Wednesday, March 28.

Queensland Minister for State Development, The Hon. John Mickel, MP, will officially commission the new MRI at 10 am on Tuesday, March 27.

Notes to the Editor
QUEENSLAND BRAIN INSTITUTE
The Queensland Brain Institute was formed in 2003 as part of the Queensland Government’s Smart State Initiative, building on a long history of neuroscience at The University of Queensland. QBI is dedicated to understanding the molecular basis of brain function and applying this knowledge to the development of new therapeutics to treat brain and mental health disorders.
