This paper includes a quick overview of common non-invasive techniques in addition to a more in-depth analysis of a body composition assessment method a technique for figuring out composition using quantitative MRI and using fat as a reference.

 For whole body measures of adipose tissue (AT), often known as fat, and lean tissue (LT), DXA and quantitative MRIs show excellent agreement,

 with linear correlations of 0.99 and 0.97 and coefficients of variation (CV) of 4.5 and 4.6% for fat (calculated from AT) and LT, respectively. With a CV of more than 20%, visceral adipose tissue showed much lower agreement.

Because of its ability to assess ectopic fat, muscle volumes, and muscle AT infiltration, as well as its speed, quantitative MRI is made possible
