Lasitha received DoD PCRP Training Award (11/23/09)

Lasitha Senadheera has recently received a postdoctoral fellowship from Department of Defense to support his research initiative in therapeutic response monitoring of radiation treatment by hyperpolarized 13C metabolic imaging. This multidisciplinary project will be mentored by Profs. L. Xing and D. Spielman (Radiology) and will be leveraged by the outstanding expertise and resources available at Stanford. Indeed, in cancer imaging, one of the major problems is the lack of biological imaging techniques for accurate tumor target definition and for assessing the therapeutic response. 13C MRSI is an exciting new area of research and has the potential to provide an unprecedented >50,000 fold signal enhancement in MR spectroscopic imaging signal. Using hyperpolarized 13C pyruvate substrate, Lasitha hope to observe the changes in pyruvate metabolism, including lactate production (which has been considered as a hallmark of tumor cells), during cancer therapeutics. Congratulations and best of luck in the proposed study.
