Steps in semi-automatic pericardial fat volume (PFV) and thoracic fat volume (TFV) quantification. At each axial slice, the reader first identifies the pericardium (Panel 1, white arrow). Five-to-seven points are manually placed along the pericardial line, and a pericardial contour is then automatically generated (Panel 2). Once this task is completed for all axial slices, the software algorithm detects and quantifies all fat voxels within the pericardial contour to generate PFV. Fat voxels outside of the pericardial contour are also detected and added to PFV to generate TFV (Panel 3).
