fMRI assessment of ischemic stroke in humans
… to salvage those cells in the penumbra region. Diffusion weighted image (DWI) is a widely used and robust tool to detect ischemia lesions. Unfortunately, DWI can only quickly and accurately detect the location of lesions, however, it cannot distinguish the infarct and penumbra, which is vital to …

Rank constrained denoising in magnetic resonance imaging
… problem for the following two MRI modalities: diffusion magnetic resonance imaging and magnetic resonance spectroscopic imaging (MRSI). For denoising magnitude diffusion weighted image series, we utilize both low-rank and edge constraints within a maximum a posteriori (MAP) framework. We …
