Neuroimaging research in Aberdeen promotes an interdisciplinary research environment including technical development, clinical and basic science expertise working with a number of brain imaging techniques to investigate all aspects of neurological and psychiatric disorders, from stratification and diagnosis to treatment planning and monitoring.
Neuroimaging research is primarily conducted with in the Aberdeen Biomedical Imaging Centre.
- Dementia & Neurodegeneration including normal ageing
- Psychiatric disorders such Schizophrenia, anxiety, autism
- Rheumatologic disorders such as Vasculitis, Lupus and Rheumatoid Arthritis
- Other disorders such as stroke and trauma, and exercise physiology
Techniques & Expertise (human and pre-clinical)
- Magnetic resonance imaging (MRI) uses magnetic fields and radio waves to produce high quality two- or three-dimensional images of brain structures without the use of ionizing radiation (X-rays) or radioactive tracers. Structural MRI allows the measurement of sub-clinical structural changes at the sub millimetre resolution.
- Functional magnetic resonance imaging (fMRI) relies on the paramagnetic properties of oxygenated and deoxygenated haemoglobin to see images of changing blood flow in the brain associated with neural activity. This allows images to be generated that reflect which brain structures are activated (and how) during performance of different cognitive tasks or during a resting state.
- Positron emission tomography (PET) measures emissions from radioactively labelled metabolically active chemicals that have been injected into the bloodstream. The emission data are computer-processed to produce 2- or 3-dimensional images of the distribution of the chemicals throughout the brain.
- Electroencephalography (EEG) is the recording of electrical activity along the scalp. EEG measures voltage fluctuations resulting from ionic current flows within the neurons of the brain.
- Computed tomography (CT) or Computed Axial Tomography (CAT) scanning uses a series of x-rays of the head taken from many different directions. This is primarily used with PET images to aid anatomical location and analysis.
- Advanced imaging techniques such as Fast-Field Cycling (FFC) and Proton Electron Double Resonance Imaging (PEDRI)
