Wasting and fatty infiltration of the muscles flanking the spine, which weakens spinal support and is linked to chronic low back pain. MRI shows the fatty change and degree of muscle loss.
Our comprehensive check-up screens for paravertebral muscle degeneration and hundreds of other conditions.
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.
Multifidus IMF (left)Intramuscular fat content in the 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.
