Laser beam measurement of abdominal sagittal diameter in obese children: a validation study
Flodmark CE, Shen W, Punyanitya M et al
Sagittal diameter (SAD) has been reported to correlate to visceral fat and cardiovascular risk factors. SAD is measured with the individual lying down, halfway between the lower rib margin and the iliac crest; it represents the mid-height of the abdomen. The aim of this study was to validate SAD measured using a recently-developed laser beam device (SADLDB) against SAD measured using MRI (SADMRI).
Thus, this laser device can be used instead of MRI to estimate SAD by using a simple correction.
