About
This studies purpose is to confirm the efficacy and efficiency of using OE-MRI and MRI with hyperpolarized gas techniques and Iodinated contrast CT scan, this will enhance understanding of CLAD pathophysiology. Moreover, this project is foundational to performing additional studies to establish if novel MRI imaging can serve as an objective confirmatory diagnostic tool for CLAD in post-transplant patients.
Full description
This studies purpose is to confirm the efficacy and efficiency of using OE-MRI and MRI with hyperpolarized gas techniques and Iodinated contrast CT scan, this will enhance understanding of CLAD pathophysiology. Moreover, this project is foundational to performing additional studies to establish if novel MRI imaging can serve as an objective confirmatory diagnostic tool for CLAD in post-transplant patients.
This observational imaging study will use 3T UTE MRI with varying oxygen levels (room air vs. 100% oxygen) to evaluate lung ventilation using oxygen enhanced imaging, in 50 healthy normal subjects (age 18-80).
Subjects will have vital signs taken, complete questionnaires and have pulmonary function test (spirometry) done, Iodinated contrast CT scan and standard of care CT scans, in addition to one MRI session that will include 6 series of scans. The MRI scans will be taken in supine position (laying on back) and include breathing room air and 100% oxygen. OE-MRI will be done in addition to MRI scans with Xenon-129.
