Wagner - My lab has found that this to be simplest method of accurately determining the polarization using multiple acquisitions of the same sample after acquiring the hyperpolarized signal. Method : The hyperpolarization intensity is acquired. Any remaining signal is removed by multiple additional high angle pulses. A delay time of 5 times tht T₁ is used before the Boltzmann intensity acquisition and a repetition delay of at least 5 T₁'s for signal accumulation.
