Brief Summary:
The aim of this study is to determine whether there is an increase in the TSPO PET signal (measured with the radioligand \[11C\]PBR28) in the lungs of patients living with PAH relative to age matched controls. If so, TSPO PET may be a useful technique to non-invasively monitor response to therapy. To do this, we will perform 2 \[11C\]PBR28 PET scans. The first will quantify the total \[11C\]PBR28 PET signal. This signal is a combination of the specific signal (VS) and the nonspecific signal (VND). The second scan will be performed following dosing with an unlabelled TSPO ligand. By directly measuring the total \[11C\]PBR28 signal (scan 1) and the nonspecific \[11C\]PBR28 signal (scan 2) we can therefore calculate the specific \[11C\]PBR28 signal, and hence the amount of TSPO in the lung.
