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.  Post-Doctoral Research Associate

David’s research focuses on applications of 129Xe 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.

Elianna Bier, BS.  Medical Physics Ph.D Candidate

Office Phone: (919) 684-7884

Email Address: elianna.bier@duke.edu

Elianna is a  Medical Physics PhD student who has focused on developing methods to acquire and interpret dynamic 129Xe spectroscopy. These dynamics are of particular interest for providing a non-invasive means to evaluate pulmonary vascular diseases.

 

 

Leith Rankine

Leith Rankine, MS.  Medical Physics PhD Candidate

Office Phone: (984) 974-8495

Email Address: leith.rankine@duke.edu

Leith is working to make connections between the fields of radiation therapy (RT) and hyperpolarized gas magnetic resonance imaging (MRI). His research focuses on developing a link between the therapeutic radiation used to cure lung cancer patients and the resulting side-effects, which can reduce lung function in cancer-survivors. The study is made possible by using the advanced functional information afforded by the hyperpolarized gas MR images acquired by Dr. Bastiaan Driehuys’ team.

 

Alexander Church, BS.  Research and Development Engineer
Office Phone: (919) 684-7839
Email Address: alexander.church@duke.edu

As a recent graduate of the joint department of Biomedical and Health Sciences Engineering at UNC-CH and NCSU, Alex is tasked with primary operation of 129Xe polarizers. Most technical problems associated with 129Xe polarizers or their equipment are handled by Alex. He is particularly savvy with hands-on work; manufacturing techniques involving CAD, CNC machining, and programming are among his primary skill set.
