My research interests encompass the physics and mathematics of imaging with Magnetic Resonance. Presently my research is directed in part towards exploration of rapid MRI scanning methods using spiral and other non-Cartesian k-space trajectories for dynamic imaging of function. Using spiral techniques, we have developed MRI pulse sequences and processing methods for mapping cortical brain function by imaging the metabolic response to various stimuli, with applications in the basic neurosciences as well as for clinical applications. These methods develop differential image contrast from hemodynamically driven increases in oxygen content in the vascular bed of activated cortex, using pulse sequences sensitive to the paramagnetic behavior of deoxyhemoglobin or to the blood flow changes. Other applications include imaging of contrast uptake in the breast.
