Measuring lung inflammation in pulmonary artery hypertension patients

Researchers want to understand if a protein called TSPO is increased in the lungs of people with pulmonary artery hypertension (a condition where blood pressure in lung arteries becomes dangerously high). They'll use two special imaging scans called PET scans to measure this protein. If successful, this imaging technique could help doctors monitor how well treatments are working without invasive procedures.

Currently, doctors don't have a good non-invasive way to track whether medications are helping pulmonary artery hypertension patients. This study aims to develop a new imaging method that could give doctors a better window into what's happening inside the lungs and help guide treatment decisions.
