Arms of the Study

Arm 1

Arm Type

Experimental

Arm Label

Hyperpolarized 129 Xenon

Arm Description

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.

Outcomes

Primary Outcome Measures

Correlation of ventilated volume predictions obtained with 129Xe MRI vs. 1H MRI
quantify the measurement agreement between the ventilated volume of healthy lungs predicted via 129 Xe MRI and the ventilated volume of the pleural cavity predicted via proton MRI

5. Study Description

Brief Summary
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.
