The cross-sectional area and thickness of the subcutaneous fatty layer of the upper abdominal plane were measured on the CT photographs of 77 persons (48 males, 29 females) . The upper abdominal plane was divided into cranial and caudal sections, and six measuring (A-F) points were made according to Erdheim's lattice line. The data were examined and compared with those of the other methods. The following results were obtained: 1) The percentage of subcutaneous fatty layer to the total cross-sectional area was 7.1 % in males and 10.2 % in females in the cranial section, and 11.1 % in males and 15.4 % in females in the caudal section. This percentage increased with age and was the highest in subjects in their fifties. 2) The thickness of the subcutaneous fatty layer was greater in the order of F-point (posterior median line), A-point (anterior median line) and B-point (mamillar line) in males, and A-point, F-point, and B-point in females in the cranial section, and, also, A-point, D-point (lumbar line) and E-point (gluteal line) in both sexes in the caudal section. 3) The thickness of subcutaneous fatty layer increased with the age at all points and was the greatest in subjects in their forties or fifties. This tendency was remarkable in twenty-and thirty-ycar-old males in the F- and A-points and in A-point in females in their twenties in the cranial section. In the caudal section, the thickness in A-point increased remarkably during the twenties and thirties in males and during the twenties in females. 4) Comparing data thus obtained with those of the other methods, the thickness of subcutaneous fatty layer in the present study corresponded to one half of value of the skin fold method, and was quite close to the direct method value in all points except A- and F-points, which were greater in this study than in others.
