### Body composition

fat free massbody composition monitorsfat-free mass
Lean body mass (LBM) is a component of body composition, calculated by subtracting body fat weight from total body weight: total body weight is lean plus fat.
The technique then estimates the percentage of body fat and lean body mass (LBM) through empirically derived equations similar to those used with underwater weighing (for the density of fat and fat free mass).

### Contrast CT

For example, the Boer formula is method of choice for LBM estimation to calculate the dose given in contrast CT in obese individuals with BMI between 35 and 40.
The dose should be adjusted in those not having normal body weight, and in such cases the adjustment should be proportional to the lean body mass of the person.
