Method for adipose tissue quantification with magnetic resonance imaging

摘要

A system and method for calculating a quantitative metric of adipose tissue using a magnetic resonance imaging (MRI) system are provided. The MRI system is used to acquire k-space data by sampling echo signals that are formed at a plurality of different echo times. From the acquired k-space data, a fat-concentration map, such as a fat-fraction map is produced. A maximum fat-concentration value is estimated from the fat-concentration map, and is used to threshold the fat-concentration map to produce an adipose mask. From the adipose mask, a quantitative metric of adipose tissue can be calculated.
