Bastiaan Driehuys, Ph.D.  Professor of Radiology

Bastiaan Driehuys directs the Xenon MRI Shared Resource at Duke. His ongoing research involves deploying and validating MR-based imaging biomarkers of pulmonary function and structure in a variety of disease areas. He helped introduce the field of hyperpolarized (HP) gas MRI, including the first animal and human studies using 3He and 129Xe. His research has turned towards exploiting solubility and chemical shifts of 129Xe to evaluate regional pulmonary gas exchange, and his team has applied that technology to patients with idiopathic pulmonary fibrosis, COPD, asthma, and pulmonary vascular disease. The group is active in developing methods to continue identifying unique spectroscopic and imaging signatures of pulmonary physiology and pathophysiology. With industry and academic experience, Dr. Driehuys’ interests span not only attacking the basic physics problems of these gases, but in their large-scale expansion and application to biomedical problems.

 

 

David Mummy, Ph.D  Assistant Professor of Radiology

Email Address: david.mummy@duke.edu

David’s research focuses on applications of <sup>129</sup>Xe MRI in human lung disease, including asthma, COPD, and interstitial lung disease. He is especially interested in how biomarkers derived from ventilation and dissolved-phase 129Xe imaging can be used clinically to aid in diagnosis, prognosis, and therapy selection and monitoring.
