Bio Statement

The focus of research in Dr. Bhattacharya's laboratory in the Department of Cancer Systems Imaging  is the development of real-time metabolic and imaging applications by hyperpolarization. We are exploring novel ways to utilize Magnetic Resonance Imaging (MRI) to create more detailed metabolic and molecular imaging studies by employing hyperpolarized, non-radioactive carbon 13 (13C) and nitrogen 15 (15N)-labeled compounds and silicon particles and nanoparticles (SiNPs) to tag specific metabolic and biochemical structures and functions that are altered in cancer. Hyperpolarized MR is a non-toxic, non-radioactive method for non-invasively assessing tissue metabolism and other physiologic properties. Hyperpolarization allows for a >10,000-fold signal enhancement relative to conventional MRI or MRS. After hyperpolarization, the signal enhancement can be retained on the metabolites of the hyperpolarized molecules for several minutes. Dr. Bhattacharya’s, lab is working on techniques to extend this relaxation time so that more detailed metabolic and molecular imaging studies can be considered.  

Magnetic Resonance laboratory is involved in three primary areas of research: 

· Real time metabolic MR imaging with hyperpolarized 13C and 15N labeled non-radioactive compounds. The goal of this research is to use mostly endogenous compounds to track different metabolic pathways in vivo in real time both in preclinical animal models and in human applications.  

·  Real-time molecular MR imaging with hyperpolarized silicon nanoparticle (SiNPs) functionalized to target specific biological functions and structure. Hyperpolarized SiNPs have opened the door for targeted functional imaging by MR that used to be in the realm of PET and SPECT. Due to the simple surface chemistry, the hyperpolarized SiNPs can serve as a nanoplatform, allowing a variety of targeting agents and potentially therapeutic drugs to be loaded onto the particles, which enables real-time targeted Theranostics imaging studies with an imaging time window of roughly one hour.  

·   High resolution MR metabolomics of animal and human tissues. To complement the real-time in vivo hyperpolarization studies, we have developed an MR based metabolomics program to generate comprehensive metabolic profiles of cancerous and non-cancerous tissues in vitro.
