Pulmonary Parenchymal 18F-FDG Uptake on PET/MRI in Pulmonary Arterial Hypertension: A Comparative Study with Healthy Controls and Prognostic Implications
Background: Pulmonary arterial hypertension (PAH) is characterized by progressive vascular remodeling and right ventricular (RV) dysfunction. 18F-FDG PET/MRI may reveal metabolic alterations in the pulmonary parenchyma and vasculature. We investigated pulmonary FDG uptake in PAH versus healthy controls and its associat...
