Summary

Summary Dr. Riederer's overall research interest is in the technical development of magnetic resonance imaging (MRI). This includes addressing fundamental limitations and considering new applications. Over the last decade Dr. Riederer's work has focused on reducing the acquisition time and improving the image quality of MR images, particularly 3D imaging of the vasculature using contrast material. His lab has developed the fundamental methods of view sharing and non-standard ordering of MR data acquisition. In ongoing work his group is adapting these techniques to accelerating the MR data collection using parallel acquisition and reconstruction techniques and multi-element arrays of receiver coils. This has provided accelerations in the range of 10 to 40Ã??????. Much of Dr. Riederer's lab work has been directed toward implementation of specific MRI techniques using real-time signal processing. Techniques developed previously include real-time fluoroscopic imaging, real-time respiratory monitoring and motion correction, fluoroscopic triggering for contrast-enhanced angiography, and real-time monitoring of multi-station peripheral MR angiography. Virtually all of his projects are directed toward some clinical area, with applications in cardiovascular, gastrointestinal, and neurological disease and cancer. Projects typically encompass technical feasibility development through to initial clinical evaluation. Dr. Riederer has served as the principal advisor to over 20 students who have received the Ph.D. degree through Mayo Graduate School. Many of these individuals have gone on to faculty positions at Mayo or other institutions nation-wide or to research positions in industry. Focus Areas -Improvements in contrast-enhanced MR angiography using acceleration techniques -High spatial resolution peripheral MR angiography using real-time tracking of the contrast bolus -Development of high-count receiver coil arrays for high SNR parallel acquisition -Development of real-time signal processing and reconstruction techniques for allowing patient-specific MRI scanning Significance to Patient Care Many of the techniques developed in Dr. Riederer's lab have been implemented by commercial MRI vendors and are used in literally tens of thousands of patient exams per day worldwide in neurological and vascular MRI exams. Ongoing projects will further aid in the detection and visualization of pathologies of the brain and body using MRI. Professional Highlights Dr. Riederer served as the President of the International Society of Magnetic Resonance in Medicine (ISMRM) at the time it was formed by merging two predecessor societies. He has served as President of the international MR Angiography Club. He has been honored as recipient of the Gold Medal of the ISMRM and as a Distinguished Mayo Investigator.
