Figure 1 The midventricular transaxial [18F]fluorodeoxyglucose (FDG) positron emission tomography (PET) images of the patients with mild (A, mean pulmonary artery pressure, 33 mm Hg) and severe pulmonary hypertension (B, mean pulmonary artery pressure, 81 mm Hg). In each image, the right ventricular (RV) free wall is at upper left, the interventricular septum at middle, and the left ventricular (LV) free wall at lower right. In the patients with severe pulmonary hypertension, the RV FDG accumulation increased compared with that in the patients with mild pulmonary hypertension. The RV standardized uptake value of FDG corrected for the partial volume effect was 6.6 and 12.7 in the patients with mild and severe pulmonary hypertension, respectively.
