Abstract

The para-hydrogen method has been used to polarize the 13C atoms in selected water-soluble molecules. The degree of polarization, achieved by recently developed methods, is in the order of 35% which is more than a factor of 105 above the thermal equilibrium polarization at 1.5 T. Earlier work has shown the potential of hyperpolarized 13C substance as a general ECF MR contrast medium. The aim of the present work has been to demonstrate the potential of using 13C CM during interventional MRI procedure aiming for real time visualization of catheter movements and the coronary arteries.
