Magnetic Resonance Imaging (MRI)

The role of Magnetic Resonance Imaging (MRI) in day to day clinical practice is growing. Gadolinium based contrast agents have traditionally been used to enhance the signal from flowing blood, allowing rapid acquisition of high spatial resolution angiograms for the diagnosis of vascular disease. The ability to view the anatomy in 3D, as well as the minimally invasive nature of MR image acquisitions, offer some advantages over more invasive x-ray angiography.

Our research has been focused on the development of MR k-space sampling and image reconstruction strategies for acquisition of high spatial resolution time-resolved MR angiograms. The ability of time-resolved 3D angiography to depict compromised flow has proven a valuable tool in assessing the severity of vascular disease, a major source of mortality and morbidity in industrialized nations.
