The present study aims at measuring abdominal fat distribution (CT scan and Lunar iDXA) in 120 adults. These data provide the possibility to validate a new method for measuring abdominal fat distribution (visceral versus subcutaneous fat) against the gold standard, CT. If validated, such a protocol based on Lunar iDXA could offer a rapid and cost effective diagnostic tool for fat distribution assessment of individuals as a basis for future personalized and health care programs.
