The annual cost of cancer treatment in the United States of America and the European Union exceed 100 billion euro. Using a combination of magnetic resonance imaging (MRI) and dissolution dynamic nuclear polarization (dDNP) the potential worldwide sa

We explore a new design approach for low frequency RF coils, where a transmit and receive array are built together in a totally rigid frame, and therefore their B and B distributions can be accurately mapped and used as prior information for SNR-opti

We report the performance of a cryogenic RF receive-only coil for 13C imaging of small animals. It is experimentally demonstrated 2-fold SNR improvement in comparison to a room temperature coil in immediate vicinity of the sample. The self-developed

Dissolution DNP has emerged as a technique to improve SNR in an NMR experiment with inherent limitation of polarization retention in solution ranging, in general, from 30 to 100 s for the interesting bio-molecules. The limitation in sensitivity and a
