| 摘要 |
The invention provides a method of hyperpolarising a magnetic resonance (MR) agent suitable for use in magnetic resonance imaging (MRI) or magnetic resonance spectroscopy (MRS) comprising the steps of: a. providing a solution comprising the MR agent suitable for use in MRI or MRS and at least one relaxation agent, the relaxation agent being a paramagnetic metal ion having an electron spin relaxation time of less than 1 x 10-10 seconds at 20°C; and b. exposing the solution to a temperature of less than 5 K and a magnetic field of at least 1 T. The relaxation agent may, for example, be dysprosium. |
