Validity of ultrasound rectus femoris quantitative assessment: A comparative study between linear and curved array transducers

Abstract

Appendicular skeletal mass is commonly used to assess the loss in muscle mass and US represents a valid, and reliable method. However, the procedural protocols are still heterogeneous. The aim of this study was to compare the intertransducers validity of thickness, width, and CSA measurements of RF muscle. The AP, LL and CSA of RF muscle were evaluated with both linear and curve probes in ten healthy subjects and six sarcopenic patients. In the healthy group the mean AP diameters measured with the linear array were significantly higher than those measured with the curved array. AP and CSA were higher in the healthy group compared with the sarcopenic group with both transducers. There was a positive correlation between weight and LL diameter, and a negative correlation between age and muscle AP, measured with the linear probe. Both linear and curved probes represent valid methods in US evaluation of the CSA of the RF muscle. However, in the healthy subjects, the thickness and width of the of the same muscle, are affected by the type of probe.

Skeletal Muscle Echo Intensity Values Differ Significantly across Ultrasound Parameter Settings

“…In applications of muscle US, it has previously been recommended to have a high degree of standardization [ 43 ]. The standardization of US measurement does include a detailed description of the device and probe, the method of measurement, and the parameter settings used for capturing the images [ 26 , 44 ]. Firstly, there is a consensus position to use a panoramic vision to assess the CSA of the (maximum) muscle bulk needed to quantify the EI [ 45 ].…”

Biceps brachii muscle cross‐sectional area measured by ultrasonography is independently associated with one‐month mortality: A prospective observational study

“…In this context, evaluation of muscle mass is a more favorable option for patients receiving palliative care. Loss of muscle mass accelerates dramatically after the age of 60, resulting in an increased risk of cognitive impairment, metabolic disorders, and mortality 41 . The European Working Group on Sarcopenia in the Elderly2 (EWGSOP2) suggests that CT, MRI, DXA, and BIA may be used to evaluate the loss of muscle mass 34 .…”

“…Se considera que el grosor del músculo es el parámetro más simple, rápido y reproducible en evaluar la masa muscular, con una buena correlación con las medidas estándar de oro, por ejemplo, el músculo recto femoral en su diámetro anteroposterior y laterolateral. 5…”
