SESSION TITLE: Pulmonary Vascular Disease II

SESSION TYPE: Original Investigation Poster

PRESENTED ON: Wednesday, October 26, 2016 at 01:30 PM - 02:30 PM

PURPOSE: Patients with Pulmonary arterial hypertension (PAH) have pathologic changes to the pulmonary vasculature including pruning of the distal vessels and dilatation of proximal vessel. This suggests that advanced CT image processing can be used to complement right heart catheterization (RHC) in the diagnosis, subtyping and monitoring of PAH. While the arterial pathologic changes have been described both qualitatively and quantitatively in the past, the distinction between arterial versus venous circulation has not been reported.
