Vasily Yarnykh, Ph.D. has 15+ year experience in various aspects of MRI physics with extensive expertise in the quantitative MRI methodology, pulse sequence development, protocol design, neurological and cardiovascular MRI applications. Dr. Yarnykh had invented several MRI technologies including quantitative MRI methods for mapping cross-relaxation parameters in tissues (CRI), efficient blood signal suppression pulse sequences for cardiovascular imaging (quadruple inversion-recovery and multi-slice double inversion-recovery), and a fast method for B1 mapping (Actual Flip-angle Imaging, AFI), which became increasingly popular over recent years. He is an author of 60 scientific articles (17 as the first author), more than 100 abstracts, and 5 patents. The main area of his research interests is the development and clinical applications of new quantitative MRI methods. The ultimate goal of Dr. Yarnykh is to bring new quantitative imaging technologies into clinical practice, where they can provide numerous benefits as both individual diagnostic tools and measures of the therapeutic effect in clinical trials.
