Echo Intensity (EI) is a promising, noninvasive, and cost-effective tool for screening sarcopenia, showing strong correlations with MRI fat fraction. Attenuation Imaging (ATI) did not correlate with MRI fat fraction or EI, indicating that further protocol adjustments and software improvements are needed for it to be useful in muscle quality assessment.
Clinical Implications: Ultrasound-based EI offers a practical alternative to MRI for early detection of sarcopenia, particularly in settings where MRI is unavailable or too costly.
Limitations: Small sample size (n=34). Time gap (up to 4 years) between MRI and ultrasound measurements. ATI measurements were limited by the region of interest (ROI) size and interference from surrounding tissues.
