Correlation Between the Distribution of Abdominal, Pericardial and Subcutaneous Fat and Muscle and Age and Gender in a Middle-Aged and Elderly Population

Figures & data

Figure 1 Schematic diagram of the measurement of abdominal fat. (A) Sagittal CT of the chest and abdomen. The marked area indicates abdominal fat (including subcutaneous fat and visceral fat), the yellow area indicates pelvic visceral fat, and the area around the heart is pericardial fat. (B) Coronal CT of the chest and abdomen. The marked area indicates abdominal fat (including subcutaneous fat and visceral fat), the yellow area indicates pelvic visceral fat, and the area around the heart is pericardial fat.
