For most types of MRI scans, a longer data acquisition period (Tau) results in data with higher SNR.  Combining this approach with the right trajectory (such as Spiral MRI) can also reduce scan times, which complements this SNR gain.  Unfortunately, long-tau imaging also presents challenges to robust imaging.  This talk will present the opportunities, challenges, solutions, successes, and remaining obstacles of our group’s journey into long-tau MRI.

Jim Pipe received his PhD in Bioengineering from the University of Michigan in 1993, and is now faculty at the Mayo Clinic in Rochester, where he directs the Magnetic Resonance Technology and Use Design group.  Dr. Pipe's research focuses on developing MRI methods that have a real, positive impact on patient care.  He is best known for his invention of PROPELLER, a method specifically designed to eliminate the blurring that results when patients move during an MRI scan.  He continues to help establish the infrastructure for many next-generation methods, such as Spiral MRI.  He also advocates for combining technology design with “use design” in order to improve patient care, while simultaneously addressing the financial pressures of healthcare and the desire for improved patient experience and empowerment.
