Special Issue Information

Dear Colleagues,

The population older than 60 years is already over 1 billion worldwide, and will have grown by over 50% in 2030. The preservation of muscle quality is a key element for healthy ageing. Ultrasound offers affordable and non-invasive opportunities for the early staging of muscle quality loss and affordable interventions. While significant progress has been made in examination protocols for clinical practice, there is a broad development space for novel ultrasound techniques that address quantification gaps.

This Special Issue is addressed to all recent developments of quantification techniques based on ultrasound sensors for assessing and monitoring muscle quality in the elderly. The scope of this Issue includes the multi-factorial assessment and preservation of muscle quality, including but not limited to muscle quantity, strength, composition, architecture, activation and metabolism. Approaches based on ultrasound sensors, physical ultrasound models, ultrasound data science, and hybrid combinations thereof are welcomed.

Ultrasound (US) is an important imaging tool for skeletal muscle analysis. The advantages of US include point-of-care access, real-time imaging, cost-effectiveness, and absence of ionizing radiation. However, US can be highly dependent on the operator and/or US system, and a portion of the potentially useful information carried by raw sonographic data is discarded in image formation for routine qualitative US. Quantitative ultrasound (QUS) methods provide analysis of the raw or post-processed data, revealing additional information about normal tissue structure and disease status. There are four QUS categories that can be used on muscle and are important to review. First, quantitative data derived from B-mode images can help determine the macrostructural anatomy and microstructural morphology of muscle tissues. Second, US elastography can provide information about muscle elasticity or stiffness through strain elastography or shear wave elastography (SWE). Strain elastography measures the induced tissue strain caused either by internal or external compression by tracking tissue displacement with detectable speckle in B-mode images of the examined tissue. SWE measures the speed of induced shear waves traveling through the tissue to estimate the tissue elasticity. These shear waves may be produced using external mechanical vibrations or internal “push pulse” ultrasound stimuli. Third, raw radiofrequency signal analyses provide estimates of fundamental tissue parameters, such as the speed of sound, attenuation coefficient, and backscatter coefficient, which correspond to information about muscle tissue microstructure and composition. Lastly, envelope statistical analyses apply various probability distributions to estimate the number density of scatterers and quantify coherent to incoherent signals, thus providing information about microstructural properties of muscle tissue. This review will examine these QUS techniques, published results on QUS evaluation of skeletal muscles, and the strengths and limitations of QUS in skeletal muscle analysis. Full article
