Hyperpolarization (HP) enhances the sensitivity of MR by several orders of magnitude and allows the detection of metabolism non-invasively and in vivo. However, well-established methods are costly, complex and require a dedicated “polarizer” next to the MRI system. SAMBADENA is, to date, the simplest and most cost-effective method to generate 13C-HP > 20 % for MRI. Within seconds HP is achieved within the MRI and little additional hardware is required. Here, the first in-vivo applications of SAMBADENA are reported, demonstrating its potential to be a fast, simple, low-cost alternative method for HP-MRI.
