Magnetic Resonance Imaging (MRI) is a powerful diagnostic technique capable of revealing the internal structure and function of the human body. However, access to commercial MRI systems is restricted due to very high purchase, installation and running costs. These MRI scanners are generally...

Heart disease is the second leading cause of death in Canada, where it affects the lives of over two million people. One modality used to detect and diagnose heart disease and other abnormalities is echocardiography or ultrasound imaging of the heart. Ultrasound imaging, compared to other...

Tracking myelination and demyelination in the brain is a crucial part of studies on neurodegenerative diseases such as Multiple Sclerosis (MS). Classic MRI techniques are unable to provide enough information about the pathology of tracts and lesions. Multi-component analysis of multi-echo data...

Fats are a fundamental building block of the human body, but accumulation of unwanted fat in and around tissues is a common pathology related to many disease mechanisms. Magnetic Resonance Imaging (MRI) offers a host of methods to differentiate water and fat signals in images or spectra, for...

Hippocampal neuroplasticity and neurogenesis in major depressive disorder: a high field MRI study
DownloadFall 2012
The hippocampus is a brain structure responsible for memory, learning, and the stress response; it is also used as a model for major depressive disorder (MDD) in preclinical studies. Preclinical models have shown that the hippocampal subfields are differentially affected by chronic stress....

Diffusion magnetic resonance imaging (dMRI) measures the diffusion (i.e. random molecular motion) of water. Since the motion of water is inhibited by cellular membranes, dMRI provides insight into the microstructural characteristics of the tissue. However, distinguishing between small anatomical...

25 years after the first sodium images of the human brain were created, sodium MRI remains on the periphery of MR research, despite intimate sodium involvement in cellular metabolism and implicated abnormal concentrations in numerous disorders. The difficulties of sodium MRI include not only...

Arterial spin labeling (ASL) is a magnetic resonance imaging (MRI) noninvasive method, capable of measuring perfusion, i.e. blood flow, with blood as an intrinsic contrast. ASL measurements of cerebral perfusion are usually acquired at very low spatial resolution (> 60mm3 voxels), for several...
