Figure 3.

Scatterplots of standardized uptake values (SUVs) from idiopathic pulmonary arterial hypertension (IPAH) patients normalized to body weight, injected dose, and blood glucose level of both left and right lungs versus various PAH clinical parameters: 6-minute walk distance (6MWD; a), mean pulmonary artery pressure (mPAP; b), pulmonary vascular resistance (PVR; c), and N-terminal prohormone of brain natriuretic peptide (NT-proBNP; d). Every dot represents a patient. No statistically significant correlations were found.
