Assessing Pulmonary Changes in HSCT

Sponsor: Children's Hospital Medical Center, Cincinnati

Summary

This will be an un-blinded, open-label study of children and adults, including those who are being evaluated for or who have undergone HSCT, those with existing respiratory conditions and/or diagnosed gas-exchange impairment, and healthy control volunteers. The participants will be male or female between 3-17 years old (children) and adults age 18 and older. The study objective is to: * To optimize the acquisition of images reflecting the "dissolved-phase" Xe distribution in the pulmonary tissues and blood (Xe gas-exchange MRI). * To develop and test Xe MRI acquisition strategies that separately image alveolar airspace distribution (ventilation), as well as Xe dissolved in pulmonary tissues versus red blood cells (RBCs). * To acquire images of Xe ventilation and dissolved-phase Xe regional distribution in the enrolled participants. * To understand the same-day variability of Xe MRI techniques. * To determine the relationship between Xe MRI and clinical measures such as pulmonary-function-test (PFT) parameters or other biological biomarkers. * To develop and optimize strategies for Xe MRI in young children including those who are unable to follow the inhalation and breath-hold instructions typical of the Xe MRI procedure.
