Reduced xenon diffusion for quantitative lung study?the role of SF6

Current issues in hyperpolarized gases in MRI: biomedical investigations and clinical applications

“…by the use of SF 6 . 20 More sophisticated techniques consist of dedicated gas delivery devices which will administer a well-defined bolus of hyperpolarized gas at a certain time point during inspiration. 21 They are necessary for standardized, quantitative and high-resolution studies.…”

Intraoperative Human Functional Brain Mapping Using Optical Intrinsic Signal Imaging

“…Whereas NMR can be performed with any atom possessing non zero spin, imaging applications prefer spin ½ nuclei because they have only two possible energy levels. Several spin ½ atoms have been used for imaging and spectroscopy applications, including 3 He [50], 13 C [51], 31 P [52], and 129 Xe [53], but by far the most common is 1 H because of its abundance in the form of H 2 O in biological material.…”

Precise measurement of magnetic field gradients from free spin precession signals of 3He and 129Xe magnetometers

“…In a gas mixture with N 2 as buffer gas, the resulting diffusion coefficients for 3 He and 129 Xe are given by [25]:…”
