Bone and muscle healthDetected by MRI

Muscle loss with fat infiltration

Age-related loss of muscle mass combined with fatty replacement of muscle tissue, reducing strength and mobility. MRI quantifies muscle volume and fat infiltration, revealing decline before it limits function.

Early detection matters

Our comprehensive check-up screens for muscle loss with fat infiltration and hundreds of other conditions.

Related biomarkers we test

Psoas major IMF (right)

Fat infiltration measurement in the right 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.

Multifidus IMF (right)

Intramuscular fat content in the right 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.

Erector spinae IMF (right)

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

Abdominal fat ratio

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.
