Research Interests
Dr. von Morze has joined the Department of Radiology at Washington University to lead a new program in hyperpolarized (HP) 13C MRI research, applying the method of dissolution dynamic nuclear polarization (DNP) first described in 2003 by Ardenkjaer-Larsen et al. The transformative signal enhancement provided by this approach (up to five orders of magnitude) offers unique potential for probing pathophysiologic metabolic changes in vivo. Primary interests are-- 1) MR engineering: Pulse sequences for localized direct and indirect detection of HP 13C magnetization, design and construction of novel radiofrequency coils for HP 13C studies and other MR hardware. 2) Development and characterization of metabolically active HP 13C probes, including associated kinetic models needed to capture fundamental metabolic information. 3) NAFLD: Supported by a new NIDDK R01 (role: co-PI), Dr. von Morze is particularly interested in applying HP 13C as well as other new MR technologies toward outstanding diagnostic problems in non-alcoholic fatty liver and steatohepatitis.
