Use of Hyperpolarized 129Xe MR Lung Imaging in Adults for Calibration (HpXeMRCal)

September 3, 2025 updated by: Children's Hospital Medical Center, Cincinnati
The goal of this study is to evaluate the usefulness of hyperpolarized (HP) 129Xe (xenon) gas MRI for regional assessment of lung function in a normal population of adults for the purposes of obtaining optimal images through MRI.

Detailed Description

Hyperpolarized 129Xe will be produced, by trained staff, using a polarizer housed at Cincinnati Children's Hospital Medical Center. Individual imaging sessions will be done on a single day and will involve administration of (maximum) 1 liter doses for up to four MRI scans. Subject will inhale hyperpolarized xenon gas and hold breath for up to 16 seconds during the MRI scans. In addition to 129 Xe MRI, a series of anatomical conventional proton MR images may also be collected. Follow up will be done one day and 30 days from the MRI date.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Hyperpolarized 129 Xenon
Administration of up to 1 liter doses of Hyperpolarized Xenon gas during MRI to optimize acquisition of images for adults vs. proton MR imaging. These scans, utilizing volunteers for calibration, may be utilized through this study to optimize the scan details.
Device: MRI
Drug: Hyperpolarized 129 Xenon
During the scans, subject will inhale hyperpolarized Xenon gas for up to 16 seconds per scan, for up to 4 separate MR scans
Other Names:
  • HP 129 Xe
