In this study on 30 volunteers, fat (considered a risk factor for some diseases) assessed using MRI, Dual Energy X-ray Absorptiometry (DEXA) and Bio-impedance analysis (BIA) are compared and correlated. The results indicate the following : MRI evaluated abdominal fat correlated well with trunk fat (DEXA) and body fat (BIA); good correlation between measurements in thigh region (MRI) and legs (DEXA); while abdominal fat is an indicator of body fat, that from the thigh region is not. The three techniques can be used interchangeably for estimating abdominal fat but MRI has the additional advantage of giving information on fat distribution.
