Imaging sodium in the brain

Sodium is critical for neuronal firing and is found in altered distributions in several brain diseases. While Sodium provides the second strongest MR-observable signal in biological tissue, its bulk signal strength is around ~20,000 times less than that of water making it difficult to reliably image, even at high field such as 7 Tesla. Our group has been developing new MRI sequences and post-processing techniques to image sodium and study sodium in different parts of the brain.

Developing methods for measuring magnetic susceptibility in the brain

MRI can detect changes in the magnetic field produced by small amounts of magnetically interacting substances like iron. In the brain, iron is found in many forms and can interact with brain cells in ways that might lead to neurodegeneration. Researchers at MBCIU are developing new ways of inferring magnetic susceptibility to detect brain iron using a method known as Quantitative Susceptibility Mapping, or QSM. We are also using QSM to study how iron is deposited in the brains of people with neurological diseases like multiple sclerosis and Alzheimer's disease.

Amyloid Image NAV4694 Positive

Predicting the onset of dementia using Positron Emission Tomography

Our PET/CT projects include Alzheimer’s research trials that image Amyloid, Tau and glucose to qualify and manage therapeutics that include anti-amyloid, anti tau and others.

We have imaged the largest cohorts in the world for trials A4, EARLY, APAD, 3D, Graduate and many more. We also have been among the first to image across the spectrum with a variety of amyloid and tau PET tracers. As well as other tracers to target MS, Parkinsons disease and schizophrenia. We also use our CT for other purposes such as imaging drill cores fossils, mummies, sheep, dogs, ancient guns, whale ear bones, cane toads, raptors, Tas Devils and for implants and training robots, and for improving the technology by developing PET/CT itself
