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 children and adults and in adults and also in children with respiratory compromise due to a variety of diseases.

Condition or disease Intervention/treatment Phase
Respiratory Disorders Drug: Hyperpolarized 129 Xenon Phase 1 Phase 2

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 (less for children) 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 phone calls will be done one day and 30 days from the MRI date.

Arm Intervention/treatment
Experimental: Hyperpolarized 129 Xenon
Administration of up to 1 liter doses of Hyperpolarized Xenon gas during MRI (less for children) to optimize acquisition of images for children and adults vs. proton MR imaging
 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 Name: HP 129 Xe


Outcome Measures

Primary Outcome Measures :
  1. Correlation of ventilated volume predictions obtained with 129Xe MRI vs. 1H MRI [ Time Frame: Day 1 ]
    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
