Brief Summary
The development of bronchiolitis obliterans syndrome (BOS) and other late onset non-infectious pulmonary complications (LONIPCs) following hematopoietic stem cell transplantation (HSCT) is associated with a significantly worse prognosis, high disease burden, and excessive health resource utilization. In this proposal, the investigators plan to examine and compare different diagnostic modalities which can provide detailed physiological and anatomical characterization of LONIPCs.

Outcome Measures
Primary Outcomes (8)
The change detected in Ventilation Defect Percent (VDP) on 129Xe MRI imaging in cross-sectional and prospectively followed cohorts.
129Xe Ventilation Defect Percent (VDP): For analysis of 129Xe static ventilation MR images we will employ the same approach as described by Kirby and colleagues to quantify the VDP to assess ventilation. VDP is expressed as a percentage.
MRIs will be performed every three months for one year.
The change detected in Apparent Diffusion Coefficients (ADC) on 129Xe MRI imaging in cross-sectional and prospectively followed cohorts.
129Xe Apparent Diffusion Coefficients (ADC): For analysis of 129Xe diffusion-weighted MR images we will employ the same approach as described by Kirby and colleagues to quantify the ADC and generate ADC maps to assess airspace size. ADC is expressed in mm\^2/s.
MRIs will be performed every three months for one year.
The change detected in Signal-to-noice Ration (SNR) on 129Xe MRI imaging in cross-sectional and prospectively followed cohorts.
129Xe Signal-to-noise Ratio (SNR): The signal-to-noise ratio will be calculated as the mean signal intensity in a region of interest within the lung divided by the standard deviation in a region of interest outside of the lung.
MRIs will be performed every three months for one year.
The change detected in forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1), total lung capacity (TLC), and residual volume (RV) in cross-sectional and prospectively followed cohorts.
FVC, FEV1, TLC, and RV will be documented in litres (L) through pulmonary function testing.
Pulmonary Function Tests (PFTs) will be performed as clinically indicated, which in this study population will be every three months for two years.
The change detected in FEV1/FVC ratio and RV/TLC ratio in cross-sectional and prospectively followed cohorts.
FEV1/FVC ratio and RV/TLC ratio will be documented; these are ratios therefore and therefore do not have units.
PFTs will be performed as clinically indicated, which in this study population will be every three months for two years.
The change detected in diffusion capacity of the lung for carbon monoxide (DLCO) and DLCO corrected for hemoglobin in cross-sectional and prospectively followed cohorts.
Diffusion capacity of the lung for carbon monoxide (DLCO) and DLCO corrected for hemoglobin will be recorded in L/min/mmHg.
PFTs will be performed as clinically indicated, which in this study population will be every three months for two years.
The change detected in DLCO divided by alveolar volume (VA) [DLCO/VA, or transfer coefficient of the lung for carbon monoxide, KCO] in cross-sectional and prospectively followed cohorts.
DLCO divided by alveolar volume (DLCO/VA, or transfer coefficient of the lung for carbon monoxide \[KCO\]) will be recorded in mL/min/mmHg/L
PFTs will be performed as clinically indicated, which in this study population will be every three months for two years.
The change detected in forced oscillometry technique (FOT) in cross-sectional and prospectively followed cohorts.
Results recorded in hertz (Hz)
Oscillometry will be recorded every three months for one year.
Secondary Outcomes (3)
Change in airway resistance and reactance over time quantified by FOT
Oscillometry will be recorded every three months for one year.
Development of Bronchiolitis Obliterans Syndrome (BOS)
Development of BOS will be documented over the study's duration (2 years).
Development of clinical outcomes of death, hospitalization for respiratory cause, or respiratory failure.
Outcomes will be documented over the study's duration (2 years).
Study Arms (2)
Established LONIPC
The first cohort will comprise of patients with established LONIPCs and the investigative procedures in this study will provide data on the scope of abnormalities and pathology across the spectrum of these conditions.
Trajectory of LONIPC
The second, prospectively followed, cohort will provide data on the sequence and temporal development of these abnormalities, and therefore provide information on the trajectory of LONIPCs
Interventions
How hyperpolarized 129Xe MRI measurements of lung structure and function change over time in a population at high risk for LONIPC related to their transplant
