Cardiovascular Reserve Evaluation in Survivors of Transplant CREST Study

This study evaluates how well the heart, lungs, and muscles are working individually, and how these systems are working together in transplant survivors. Information collected in this study may help doctors to understand why hematopoietic stem cell transplant survivors are at higher risk for developing cardiovascular disease.

Comparison of Cardiopulmonary Fitness Level With Normal Values After COVID-19

COVID-19 (Coronavirus disease 2019) is a new infectious disease caused by a virus named as SARS-CoV2 (Severe Acute Respiratory Syndrome Coronavirus-2). Although it can have a devastating effect on many organs, the respiratory tract is particularly affected. In the course of the disease, a wide clinical spectrum is observed, from …

Hyperpolarized 129Xe Magnetic Resonance Imaging for Evaluation of Radiation-Induced Lung Injury in Subjects Undergoing Thoracic Irradiation

The purpose of this work is to perform hyperpolarized (HP) 129Xe MRI in human subjects undergoing thoracic radiation therapy (RT), both before, during and following RT. HP 129Xe MR images will be analysed to provide maps of ventilation (V), perfusion (Q), apparent diffusion coefficient (ADC) and gas exchange. These results …

MRI of Lung Structure and Function in Preterm Children

The MRI tools developed by the investigators are well positioned for assessing regional changes in lung structure and function in preterm children with bronchopulmonary dysplasia (BPD), in which airway limitation similar to asthma, alveolar simplification similar to emphysema and pulmonary vascular stunting are expected. To the investigator's knowledge, the combination …

Close Assessment and Testing for Chronic Graft Versus Host Disease CATCH Study

This trial observes and collects samples from patients before and after stem cell transplantation to learn more about how and why a complication called chronic graft-versus-host disease (GVHD) develops after stem cell transplantation. Performing close observation and various types of testing may enable doctors to notice symptoms or problems sooner …

Measurement of Lung Area at Chest Radiography to Define the Prognosis in Newborns With CDH

CDH represents a malformative disorder characterized by an incomplete diaphragm formation. This results in poor lung development (pulmonary hypoplasia), associated with altered vascularization of the lung (pulmonary hypertension), determining respiratory and cardiovascular insufficiency at birth. CDH shows high mortality and significant morbidity so that its prognostic evaluation remains challenging. The …
