Figure 1.

Pericardial fat and intrathoracic fat in an axial image, showing that the pericardial sac was defined as the border between pericardial and intrathoracic fat (A) and three-dimensional reconstructions of pericardial fat (B) and total thoracic fat (C). Intrathoracic fat was calculated by subtracting pericardial fat from total thoracic fat. For this subject, pericardial fat volume was 153 cm³, intrathoracic fat volume was 287 cm³, and VAT volume was 1865 cm³.
