Chest adipose tissue distribution in patients with morbid obesity

  Figure 1. Measurement of the epicardial adipose tissue thickness (EAT). Reconstruction plane was adjusted to be perpendicular to the long axis of the heart and located at the base of the ventricles. Calipers were placed at the 25% (EAT sup), 50% (EAT mid) and 75% (EAT inf) of the right ventricle’s free wall, between myocardium and the visceral epicardium and perpendicular to the surface of the heart

• 

  Figure 2. Measurement of the pericoronary fat thickness (PCF). Standard axial view is used. Calipers were placed in the regions of right coronary artery (PCF RCA), left coronary artery (PCF LCA) and the left circumflex (PCF LCX). Maximal distance between myocardium and the visceral epicardium was measured. To avoid overestimation of PCF thickness due to obliquity, measurements were done only on sections where surface of the heart was perpendicular to the slice plane

• 

  Figure 3. Measurement of the intra-pericardial fat volume (IPF vol). Results obtained by manual, slice-by-slice tracing of the pericardium on axial sections, beginning at the level of pulmonary artery bifurcation and ending with the last slice on which pericardium was recognizable. Attenuation values from –200 HU to –30 HU were used to identify fat voxels

• 

  Figure 4. Measurement of the intra-thoracic fat volume (ITF vol). Results obtained by manual, slice-by slice tracing of the mediastinum boundary on axial sections, beginning at the level of pulmonary artery bifurcation and ending at the surface of the diaphragm. Attenuation values from –200 HU to –30 HU were used to identify fat voxels
