“…During the past few years, several studies have been published on SWE of human tendons (5-17) and muscles (18)(19)(20)(21)(22)(23)(24)(25)(26)(27)(28)(29), with promising results. The majority of these studies are experimental (5,6,(9)(10)(11)(12)(13)(14)(16)(17)(18)(19)(20)(21)(22)(23)(24)27,29,(31)(32)(33) with a smaller number of clinical studies (7,8,15,26,28,30,34,35).…”

“…There are a few studies on SWE of the supraspinatus muscle (27,28). Itoigawa and collaborators (27) evaluated supraspinatus muscle stiffness in six shoulders of three young healthy volunteers using an Aixplorer US scanner to explore the potential feasibility of SWE in combination with B-mode US to measure the stiffness of the supraspinatus muscle along the long axis of the muscle fibers and obtain key information about muscle extensibility, which is an important factor for rotator cuff repair treatment planning.…”

“…Promising results have been published in the recent literature on the utility of SWE in the evaluation of several traumatic and pathologic conditions of various musculoskeletal soft tissues, including tendons (5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17), muscles (18)(19)(20)(21)(22)(23)(24)(25)(26)(27)(28)(29), nerves (30)(31)(32), and ligaments (33)(34)(35).…”

In the past 2 decades, sonoelastography has been progressively used as a tool to help evaluate soft-tissue elasticity and add to information obtained with conventional gray-scale and Doppler ultrasonographic techniques. Recently introduced on clinical scanners, shearwave elastography (SWE) is considered to be more objective, quantitative, and reproducible than compression sonoelastography with increasing applications to the musculoskeletal system. SWE uses an acoustic radiation force pulse sequence to generate shear waves, which propagate perpendicular to the ultrasound beam, causing transient displacements. The distribution of shear-wave velocities at each pixel is directly related to the shear modulus, an absolute measure of the tissue's elastic properties. Shear-wave images are automatically coregistered with standard B-mode images to provide quantitative color elastograms with anatomic specificity. Shear waves propagate faster through stiffer contracted tissue, as well as along the long axis of tendon and muscle. SWE has a promising role in determining the severity of disease and treatment followup of various musculoskeletal tissues including tendons, muscles, nerves, and ligaments. This article describes the basic ultrasound physics of SWE and its applications in the evaluation of various traumatic and pathologic conditions of the musculoskeletal system.

An investigation into the variability between different shear wave elastography systems in muscle

Aims: The reliability and agreement between shear wave elastography (SWE) systems using different acquisition methods in muscles is not yet established. The objectives were to determine the reliability of a new SWE system on normal resting muscles using different acquisition methods and to compare its performance to an established state-of-the-art system.Material and methods: Small, medium and large ROI sizes in addition to longitudinal, oblique and transverse orientations over five different locations within the rectus femoris muscle were tested using the new system. Results were compared to the established system to test for inter-system reproducibility.Results: Lowest within-subject coefficient of variance (4.3%) andshear wave velocity (1.83 m/s) were associated with the medium ROI and longitudinal orientation from the lateral location. This combination resulted in a strong internal agreement of intra-class correlation of 0.76 (0.57–0.89) for the new system and an almost perfect agreement of 0.92 (0.82–0.97) for the established. Inter-system reproducibility for the best combination was 0.71 (0.48–1) with a mean velocity difference ±95% limits of agreement of 0.07±0.49 m/s.Conclusions: Altering SWE acquisition methods can produce variable results. The new system produced reliable results that are comparable with but not as reliable as the established.

“…Away from the Achilles tendon, ultrasound elastography has been used to assess supraspinatus muscle and tendon (Figure 3), with tendinosis predominantly being shown as tendon softening, but also regions of increased stiffness, purported to represent reparative fibrosis (Figures 4 and 5)[37-39]. Strain elastography has also been used around the elbow to assess the common extensor tendon.…”

Ultrasound is an essential modality within musculoskeletal imaging, with the recent addition of elastography. The elastic properties of tissues are different from the acoustic impedance used to create B mode imaging and the flow properties used within Doppler imaging, hence elastography provides a different form of tissue assessment. The current role of ultrasound elastography in the musculoskeletal system will be reviewed, in particular with reference to muscles, tendons, ligaments, joints and soft tissue tumours. The different ultrasound elastography methods currently available will be described, in particular strain elastography and shear wave elastography. Future directions of ultrasound elastography in the musculoskeletal system will also be discussed.

Quantitative Shear-Wave US Elastography of the Supraspinatus Muscle: Reliability of the Method and Relation to Tendon Integrity and Muscle Quality

Abstract: Shear-wave elastography is reproducible for assessment of the SSP muscle. Mean normal SSP SWV is 3.0 m/sec ± 0.5. SWV decreases with increasing fat content (Goutallier stage 0-III) and increases in the final stage of fatty infiltration (Goutallier stage IV).
