Summary of Thesis

       This year the Canadian Cancer Society predicts that 2,600 Canadians will be diagnosed with brain cancer, and 1,750 will die of the disease. Magnetic resonance imaging (MRI) generates excellent soft-tissue contrast and is the most common method to diagnose and monitor brain cancer. MR images are often formed by measuring the “T2 relaxation” of protons attached to water molecules, after the protons have been excited using a pulse of radio-frequency energy. T2 relaxation in tissue is influenced by cellular-scale water compartments. Pathology alters tissue structure and may cause significant changes in T2 relaxation.
      Quantitative T2 (qT2) is a specialized field of MRI research that examines the fundamental T2 relaxation process to provide quantitative information about water compartmentalization in vivo. My research was focused on developing a new high- resolution “voxel-based” technique for quantitative T2 MRI analysis. This technique produces spatial color maps showing tissue water fraction and geometric mean T2. These maps can be interactively manipulated and compared to reveal alterations to water compartmentalization caused by pathology.
       I analyzed MR scans from normal control mice and mice with invasive gliomas induced from human brain tumor initiating cells. Results were compared to ex vivo histological stains produced from the same animals. My analysis was able to accurately identify tumor infiltration not visible on standard MRI. This new technique may be useful for scientists and clinicians who wish to identify and monitor pathology in vivo.

Research from Mike Roberts and Jeff Packer has been featured on Nvidia Corporation's website. The research describes a new massively parallel algorithm that will improve treatment planning and assessment by allowing physicians to quickly, accurately, and reliably identify and measure objects in 3D medical images. The new algorithm is 14x faster than previous algorithms without affecting accuracy.

"Virtual biopsy is a major research focus of Dr. Ross Mitchell a medical computer scientist at the University of Calgary. "Virtual biopsy uses analytical methods to extract information about a patient's genetics from their images. We can't see genes directly with medical imaging—the spatial resolution is too poor—but medical images can detect other biochemical and physical information related to genes. We may be able to use that information to non-invasively diagnose diseases like stroke, multiple sclerosis, and brain cancer," explains Dr. Mitchell."

New podcast released

thor — 2009-12-22T19:47:39Z

We have released a new podcast of a lecture Thorarin Bjarnason gave at Oxford. His talk, titled Quantitative T2 (qT2): more than just a shade of grey, is about using T2 relaxation in MRI to determine subvoxel information. Typically, T2 relaxation is only used as a contrast mechanism. In this lecture Bjarnason introduces the concept of qT2, highlights some interesting literature, and discusses his PhD research on this topic.
