Brain Imaging

The brain can be imaged in a variety of different ways, the choice of imaging modality depending on the research question being answered. Magnetic Resonance Imaging is a very versatile modality that can provide structural and functional data with new developments allowing increasingly complex analyses. Magnetic resonance spectroscopy provides a measure of brain chemistry. Computed Tomography provides more basic structural data, but a strength of CT is the ability to obtain contrast based regional blood flow and blood volume data. Positron Emission Tomography can provide exquisite quantitative data on the distribution of radiolabled compounds. These can be standard labeled compounds such as glucose or dopamine or custom labeling of test compounds can be developed. These images are routinely co-registered to CT images for precise anatomical location of the regions of uptake of the radiopharmaceutical.

Brain imaging data is well correlated with cognitive function in several species. CanCog can provide cognitive testing services to support imaging data in several species

Structural Brain Imaging

Functional Brain Imaging

  • Dynamic contrast perfusion to assess blood brain barrier permeability and regional cerebral blood flow using either MRI or CT
  • PET/CT imaging with additional coregistration to MRI images if required to quantify glucose uptake
  • Imaging of brain tissues using standard PET radiopharmaceuticals eg F-18 DOPA
  • Imaging of brain tissues with custom developed radiopharmaceuticals linked to specific naturally occurring brain chemicals or novel compounds
