The research interests of Stephen J. Riederer, Ph.D., are in the technical development of magnetic resonance imaging (MRI). This includes use of the underlying MRI physics, development of new imaging techniques and implementation that addresses clinically important problems.
Previous projects have been in the development of fast scanning methods such as multishot echo-planar imaging for the liver and brain, fast spin-echo fluid-attenuated inversion recovery (FLAIR) imaging of the brain, and rapid gradient-echo imaging with nonstandard (centric) phase encoding orders. Contemporary projects include adapting these methods to rapid contrast-enhanced magnetic resonance angiography and dynamic contrast-enhanced perfusion imaging.
Another major aspect of Dr. Riederer's research is real-time signal processing. Developments have included magnetic resonance fluoroscopy, real-time line scanning and operator-interactive triggering for contrast-enhanced magnetic resonance angiography. Current studies include high speed, patient-specific optimization of parallel acquisition.
Dr. Riederer has long been active in the training of graduate students. He teaches didactic courses at Mayo Graduate School in MRI physics, and he has mentored more than two dozen students to Ph.D. degrees, many of whom are now active in research careers of their own.

Significance to patient care
Dr. Riederer's research team interacts routinely with radiologists in the in vivo evaluation of new techniques. Many of the methods developed in Dr. Riederer's laboratory have been implemented commercially and are used daily in MRI systems worldwide.
