Default Hyperpolarized H2O MR angiography

From The DNP-NMR Blog:

Hyperpolarized H2O MR angiography


Ardenkjaer-Larsen, J.H., et al., Hyperpolarized H2 O MR angiography. Magn Reson Med, 2014. 71(1): p. 50-6.


http://www.ncbi.nlm.nih.gov/pubmed/24243653


PURPOSE: The aim of this study was to demonstrate that dissolution- dynamic nuclear polarization is capable of hyperpolarizing water protons and that the signal from the hyperpolarized bolus injection can be exploited in angiographic applications. METHODS: We hyperpolarized water/glycerol using dynamic nuclear polarization followed by dissolution in D2 O. RESULTS: A water (1) H signal enhancement of 77 times compared with 4.7 Tesla was obtained. This corresponds to a polarization of 3.5% for the 3.9 mol/L (1) H in D2 O . Moreover, a T1 in excess of 20 s was achieved. CONCLUSION: The use of hyperpolarized water as a contrast agent presents a new opportunity to obtain MRA images with high contrast-to-noise in a fraction of a second.

Cardiovascular Applications of Hyperpolarized MRI
From The DNP-NMR Blog: Cardiovascular Applications of Hyperpolarized MRI Tyler, D., Cardiovascular Applications of Hyperpolarized MRI. Curr Cardiovasc Imaging Rep, 2011. 4(2): p. 108-115. http://dx.doi.org/10.1007/s12410-011-9066-8 Many applications of MRI are limited by an inherently low sensitivity. Previous attempts to overcome this insensitivity have focused on the use of MRI systems with stronger magnetic fields. However, the gains that can be achieved in this way are relatively small and increasing the magnetic field invariably leads to greater technical...
