Overview
Our research focuses on magnetic resonance imaging (MRI) research with hyperpolarized 129Xe gas. We are at at the forefront of developing this novel technology for imaging the lungs of patients with pulmonary disease. We currently have multiple, ongoing NIH and industry-sponsored studies invovling this technique. Hyperpolarization is a laser-based process that enhances the MRI signal of xenon gas by a factor of 100,000 to allow for high-resolution, non-invasive MRI of pulmonary function. In addition to our research program, this technology was recently FDA approved and efforts are underway to implement it clinically.
Current studies are applying 129Xe MRI for early diagnosis and monitoring of interstitial and pulmonary vascular diseases. Our group, which is comprised of MRI scientists and radiologists, works closely with colleagues in pulmonary medicine. Our laboratory provides research opportunities to Ph.D., Masters, and medical students as well as select undergraduate students.
