The proportion of abdominal fat relative to total body fat. This measurement helps assess fat distribution patterns, which can be more clinically relevant than total fat alone. Higher abdominal fat ratios are associated with increased metabolic and cardiovascular risks.

Fat stored beneath the skin in the abdominal region. While still contributing to overall adiposity, ASAT is generally considered less metabolically harmful than visceral fat. However, excessive ASAT can still contribute to insulin resistance and metabolic dysfunction, albeit to a lesser degree than VAT.

Abdominal Subcutaneous Adipose Tissue index is the volume of subcutaneous fat in the abdominal region adjusted for height. Like other fat indices, it's normalized by dividing by height squared to enable better comparison between individuals of different body sizes.

A normalized measure of all abdominal fat (both visceral and subcutaneous) adjusted for height. It's calculated by dividing total abdominal fat volume by the square of height, allowing for standardized comparison between individuals of different body sizes.

The sum of all adipose tissue in the abdominal region, including both visceral and subcutaneous compartments. This measurement provides an overall assessment of abdominal adiposity.

Visceral Adipose Tissue index is the volume of visceral fat adjusted for height. It normalizes VAT measurements across individuals of different heights, allowing for more accurate risk assessment. Higher VAT index values indicate increased cardiometabolic risk independent of BMI.

The ratio of visceral adipose tissue to subcutaneous adipose tissue. This measure helps evaluate fat distribution patterns, with higher ratios indicating relatively more visceral fat, which is associated with greater metabolic risk than subcutaneous fat.

Fat stored around internal organs within the abdominal cavity. VAT is metabolically active and produces inflammatory cytokines and hormones that affect insulin sensitivity and metabolism. Excessive VAT is strongly linked to metabolic syndrome, cardiovascular disease, type 2 diabetes, and certain cancers

Intramuscular fat percentage in the right/left erector spinae, a group of muscles that straighten and rotate the back. Increased IMF is associated with muscle quality deterioration and potential functional decline.

Volume measurement of the right/left erector spinae muscle group. Reduced volume may indicate disuse, aging effects, or pathological conditions affecting back musculature.

Intramuscular fat content in the right/left multifidus muscle, a deep back muscle important for spinal stability. Higher IMF values indicate fatty infiltration which may correlate with reduced muscle function and back pain.

Fat infiltration measurement in the right/left psoas major muscle, which connects the lumbar spine to the femur and is essential for hip flexion. Higher IMF values typically indicate poorer muscle quality.

Fat infiltration measurement in the right/left psoas major muscle, which connects the lumbar spine to the femur and is essential for hip flexion. Higher IMF values typically indicate poorer muscle quality.

Size measurement of the right/left psoas major muscle. This core muscle's volume correlates with overall physical function and can serve as a biomarker for frailty or fitness.
