1. Muscle ultrasound may help detect early signs of insulin resistance and reduced muscle mass in patients with obesity.
2. Elevated muscle echo intensity (MEI) correlated with insulin resistance and impaired insulin sensitivity.
3. MEI demonstrated an inverse correlation with muscle mass indices, indicating potential early sarcopenia.
4. Ultrasound offered practical advantages over traditional methods, such as cost-effectiveness and portability.
5. The study emphasized the need for larger samples and further investigation into biological factors contributing to elevated MEI, such as fat infiltration and inflammation in skeletal muscle.
