Figure illustrating epicardial and thoracic fat quantification. Left top: white arrow points to the pericardial sac as a thin band enveloping the heart. Right: pericardial sac (closed curve in blue) is traced by an experienced imaging cardiologist by placing 6–10 control points (shown as blue circles) on the pericardium. Left bottom: Fat quantification results. Red overlay represents epicardial fat enclosed by the pericardium. Yellow overlay represents fat outside the pericardium. Color overlay (Red + Yellow) represents total thoracic fat.
