[Influences of probe application on the measurement of subcutaneous thickness using A-mode ultrasonography ].
The purpose of the present study was to investigate the effects of the way of probe application on the values of subcutaneous fat thickness by use of A-mode ultrasonography . Subjects were six healthy male adults ranging in age from 19 to 35 years. Scapular, triceps, supra-iliac, abdomen, and thigh were chosen for the measurement sites. Observed values of subcutaneous fat decreased with the increase of pressure at scapular, supra-iliac, and abdomen for relatively fatty subjects, but not for lean subjects. However, the values showed little change at triceps and thigh for all subjects. There was no relation between the pressure of probe and the stability of the value. The values were also influenced by the displacement of the probe on skin. Moreover, it was shown that the difference of the angle between probe and skin influenced the values of subcutaneous fat thickness. A-mode ultrasonography++ has many advantages, if it is properly operated considering the above problems.
