Study Details

Study Description

Brief Summary

This research is a study to test the reliability of Hyperpolarized Xenon MRI (HXe MRI) as a biomarker in interstitial lung disease. The study is a non-randomized study to evaluate the test-retest performance of HXe MRI in Idiopathic Pulmonary Fibrosis (IPF) and chronic Hypersensitivity Pneumonitis (cHP) as a non-invasive biomarker of disease severity and prognosis. The study will include approximately 15 subjects with IPF, 15 subjects with cHP and 10 sex and age-matched normal controls performed across 3 sites.

Arms and Interventions

Arm Intervention/Treatment
Experimental: Subjects with Progressive Interstitial Lung Disease

Assess the intra-visit reliability and sensitivity to progression of 129Xe MR imaging measurements using a standardized imaging protocol in subjects with IPF and cHP.

Drug: Hyperpolarized Xe129
Whether magnetic resonance imaging (MRI) using inhaled hyper-polarized 129 Xenon gas can help visualize impaired lung function to assess patients with cHP and IPF.

  • HP 129Xe
  • Outcome Measures

    Primary Outcome Measures

    1. RBC:Barrier Ratio [RBC:Barrier will be assessed at Baseline and at 6 months.]

      RBC:Barrier ratio will be determined using 129 Xenon MRI in 2 successive scans on two separate days 6 months apart. Same-day Repeated measures will be used to assess reliability of RBC:Barrier. Data acquired at 6 months will be correlated with FVC.
