A system and method for using hyperpolarized noble gases together with an
appropriately designed and optimized magnetic resonance imaging pulse
sequence to rapidly acquire static or dynamic magnetic resonance images.
The strong magnetic resonance signal from hyperpolarized gases, combined
with the present magnetic resonance imaging technique, presents the
opportunity for the imaging of gases with both high spatial and high
temporal resolution. One potential application for such a method is the
direct, dynamic visualization of gas flow, which would be extremely
useful for characterizing a variety of fluid systems. In the medical
field, one such system of substantial importance is the lung. The system
and method provides for visualizing regional ventilatory patterns
throughout the respiratory cycle with high temporal and high spatial
resolution. The low sensitivity to susceptibility artifacts permits good
image quality to be obtained in various orientations. Depending on the
application, temporal resolution can be traded for anatomical coverage.
Such application of dynamic imaging of the lung using hyperpolarized
gases will provide unique information on the physiology and
pathophysiology of the lung, and has the potential for many
clinically-relevant applications.
