Project List

   Currently we have projects in the following areas:
   Dynamic Speech Imaging
   Imaging Microvascular Blood Flow with FENSI
   Magnetic Susceptibility Estimation/Correction
   Structural Multiparametric Imaging
   Functional Imaging
   High Resolution Diffusion Tensor Imaging


	Dynamic Speech Imaging Fast imaging of soft tissue in the velar region is necessary for understanding the normal function of muscles use in speech. This is a spiral FLASH image. For more information see: DRS 2008 Poster

	Imaging Microvascular Blood Flow with FENSI Microvascular blood flow in the brain represents the functionally relevant flow in arterioles, capillaries and venules. Flow is usually measured indirectly by tagging spins at a distance from the region of interest in a technique called arterial spin labeling (ASL). Quantitation of ASL suffers from deviations in transit time. We developed a technique called Flow ENhancement of Signal Intensity (FENSI) to provide a direct, quantitative, and directionally-sensitive measure of microvascular blood flow. See Magnetic Resonance in Medicine 58(2): 396-401, 2007.

	High Resolution Localized Diffusion Imaging An MR acquisition can be sensitized to directionally specific diffusion in the myelinated white matter axons in the brain. This can be potentially useful in making inferences on connectivity between cognitive processing centers or inferring health of neurons. See paper in October Magnetic Resonance in Medicine!
