Imaging techniques

We use & develop a variety of advanced imaging techniques to study common medical problems & physiology.

Cerebrovascular-reactivity (CVR)

Cerebrovascular reactivity is the change in cerebral blood flow in response to a vaso-active stimulus.

Compressed sensing

Compressed sensing is a generic method of reconstructing signals & images from fewer measurements (i.e. fewer samples) than are required by conventional theory.

Diffusion MRI & Tractography DTI

Diffusion MRI (dMRI) measures the mobility of water molecules in the brain.

Electroencephalography (EEG)

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.

Functional MRI (fMRI)

Functional MRI (fMRI) is a non-invasive tool for studying brain function, both in healthy volunteers and clinical patients.

Perfusion Imaging

Perfusion is defined as the passage of fluid through the lymphatic system or blood vessels to an organ or a tissue. The practice of Perfusion scanning, aims to ‘see’ the passage of fluids through body tissues.

Permeability Imaging

Permeability imaging (dynamic contrast-enhanced MRI) involves the repeated acquisition of T1-weighted MR images following injection of a contrast agent such as gadolinium.

PET-MRI

This technique combines an MRI scanner with fully integrated PET detectors allowing for the simultaneous acquisition of PET data during the application of regular MRI techniques.

Spectroscopy

Magnetic Resonance Spectroscopy (MRS) is a non-invasive diagnostic test for measuring biochemical changes in the brain. This provides valuable information regarding the brain’s chemistry by using the same resonance phenomenon as MR imaging (MRI).

Structural MRI

Structural magnetic resonance imaging (MRI) is a non-invasive technique for examining the anatomy and pathology of the brain (as opposed to using functional magnetic resonance imaging [fMRI] to examine brain activity. This produces images which can be used for clinical radiological reporting as well as for detailed analysis.

Temperature Mapping

BRIC uses Magnetic Resonance Spectroscopic (MRS) to collect data used to estimate temperature on a voxel by voxel basis.
