In previous experiments by the authors, in which hyperpolarized 129 Xe was dissolved in fresh blood samples, the T 1 was found to be strongly dependent on the oxygenation level, the values increasing with oxygenation: T 1 was about 4 s in deoxygenated samples and about 13 s in oxygenated samples.

## Abstract In cerebral blood volume (CBV)โweighted functional MRI (fMRI) employing superparamagnetic contrast agent, iron dose and blood oxygenation level dependent (BOLD) contamination are two important issues for experimental design and CBV quantification. Both BOLD and CBVโweighted fMRI are bas
## Abstract ## Purpose To evaluate the function of the parotid glands before and during gustatory stimulation, using an intrinsic susceptibilityโweighted MRI method (blood oxygenation level dependent, BOLDโMRI) at 1.5T and 3T. ## Materials and Methods A total of 10 and 13 volunteers were investi
## Abstract An MR line scan protocol has been used to measure relaxation parameters (__T__~1~ and __T__~2~) in isolated, blood perfused rabbit hearts at various blood oxygenations. Hearts were retroโgradely perfused at 37ยฐC with a cardioplegic solution (modified St. Thomas' solution) containing she
Size dependency of the relaxation time T 1 was measured for laserpolarized 129 Xe gas encapsulated in different sized cavities made by glass bulbs or gelatin capsules. The use of laser-polarized gas enhances the sensitivity a great deal, making it possible to measure the longer 129 Xe relaxation tim
