MRI

Magnetic Resonance Imaging (MRI) uses magnetic fields and radio waves to create images of bodies or other items placed in the bore of the MRI scanner. The scanner can be “tuned” to record specific static or dynamic aspects of the brain and body. Structural brain scans can provide sub-millimetre resolution images of the brain’s structure, used to identify size, shape and location of key brain structures, as well as the density of grey or white matter. Diffusion Tensor Imaging (DTI) provides a detailed picture of white matter nerve fibre tracts – the brain’s main inter-region communication “highways”. Magnetic Resonance Spectroscopy (MRS) can provide information about the amount of specific chemicals – neurotransmitters for example – in different brain regions.

Blood Oxygenation Level Dependent (BOLD) imaging and Arterial Spin Labeling (ASL), also known as Perfusion imaging provide information about the flow of blood to and from different brain regions, which changes as a function of short-term and long-term neural activity. These two techniques form the basis for functional MRI (fMRI).
