Figure 1From: Pulmonary vascular remodeling and right heart failure in pulmonary hypertension: future role of positron emission tomography in decoding the enigma 11 C-Acetate wash-out scans of the lungs of a control subject (upper panel) and a patient with pulmonary arterial hypertension (PAH, lower panel. There is a suggestion of a decreased acetate wash-out in the PAH patient, which is compatible with a lower oxygen uptake. This would comply with a metabolic shift in the lung characterized by a decreased glucose oxidation and an increased reliance on anaerobic metabolism. These findings need to be confirmed in a larger group of patients and controls.Back to article page
