Non-invasive in vivo fat composition determination using the power of 7T MRS. Proton and carbon-13 MRS gives information about levels of mono- and poly-unsaturation, about ratios of omega-6 to omega-3 fatty acids, and about levels of trans-fatty acids. We are investigating correlations of diet (and fat intake) to X-syndrome and cancer prevalence.
I am involved in several aspects of MRI and MRS research, in the area of metabolism and its connections to diabetes, as well as in the area of developing new PARACEST and CEST-based contrast agents for MRI. I am involved in pulse sequence programming, image and spectro processing, image quality testing, and RF coil construction.
The novel area of hyperpolarized 13C MRI and MRS as applied for metabolic studies is also something that I am interested in.
