Current Projects

1. Utility of dual energy CT in children; in particular as it pertains to lung perfusion in congenital heart disease. This is a retrospective study looking at patients that were imaged using dual energy CT that have pulmonary arterial disease.

2. Utility of hyperpolarized 129Xe functional pulmonary MRI in children with interstitial lung disease. This is a collaborative project with Dr. Jonathan Rayment.
