Biography & Affiliation


Although hyperpolarized gases have been used to investigate regional pulmonary structure and function since the late 1990, the technology was not widely disseminated, because it relied on the rare and expensive stable isotope 3He. Dr. Cleveland helped pioneer the use of more readily available 129Xe, paving the way for clinical hyperpolarized gas MRI. Dr. Cleveland also helped expand the limits of preclinical MRI by demonstrating the feasibility of high resolution HP 129Xe imaging in rats and mice and by demonstrating the the first, in vivo molecular imaging applications of HP gases.
