Hyperpolarization by dissolution dynamic nuclear
polarization (DNP) allows enhancing the signal intensity
of insensitive nuclear spins such as
6
Li.
The long in vivo T
1
of
6
Li
makes it an attractive hyperpolarized contrast agent for
real-time perfusion imaging. The present study
demonstrates the feasibility of imaging in real time the
cerebral distribution of hyperpolarized
6
Li
at pharmaceutical concentration. As lithium salt is used
for treating bipolar disorder, this opens new
opportunities to assess the effect of Li
+
on
cerebral function.
