3He spin exchange cells for magnetic resonance imaging
2002
Journal of Applied Physics
We present a protocol for the consistent fabrication of glass cells to provide hyperpolarized ͑HP͒ 3 He for pulmonary magnetic resonance imaging. The method for producing HP 3 He is spin-exchange optical pumping. The valved cells must hold of order 1 atm•L of gas at up to 15 atm pressure. Because characteristic spin-exchange times are several hours, the longitudinal nuclear relaxation time T 1 for 3 He must be several tens of hours and robust with respect to repeated refilling and
