Normalized metrics for visceral adipose tissue mass and volume estimation

摘要

A method and system for determining normalized metrics for visceral adipose tissue (VAT) mass and volume estimation. The normalized metrics including a VAT average cross-section determined by dividing a VAT volume by a height of the abdominal region of interest, and a VAT linear mass density determined by dividing the VAT mass by a height of an abdominal region of interest.

主权项

1. A method for determining visceral adipose tissue (VAT) of a subject, the method comprising:
performing a dual-energy X-ray scan of the subject; generating at least one image of the subject from the dual-energy X-ray scan; identifying a region of interest on the at least one image; determining a subcutaneous adipose tissue (SAT) composition for each of a plurality of sections of the region of interest; determining a VAT mass and/or a VAT volume for the region of interest based on the determined SAT composition for each of the plurality of sections; and determining a normalized metric for VAT linear mass density by dividing the VAT mass by a height of the region of interest.
