“…This trend may be attributed to increased research interest in sarcopenia as well as to a broad application in various disorders presenting with muscle pathology. 32 A wide range of normal and abnormal muscle USE appearances are reported, without established reference values. 33 However, contralateral muscle proved to serve as a good internal control because bilateral muscle assessment did not show significant differences in muscle stiffness (►Fig.…”

Ultrasound elastography (USE) is becoming an important adjunct tool in the evaluation of various musculoskeletal (MSK) traumatic conditions and diseases, with an increasing number of applications and publications in recent years. This rapidly evolving technique enhances the conventional ultrasound (US) examination by providing information on the elastic properties of tissue alongside the morphological and vascular information obtained from B-mode US and Doppler imaging. Those performing USE must have basic knowledge of its proper imaging techniques and limitations. In this review article, we place the USE in historical perspective and discuss basic techniques and current applications of USE in the evaluation of various traumatic and pathologic conditions of fasciae, nerves, muscles, tendons, ligaments, and MSK soft tissue masses.

“…17 There is now increasing interest in the use of ultrasound elastography for the evaluation of neuromuscular pathologies. 18,19 Elastic moduli are used to quantify the differences in tissue elasticity ( Figure 1). Essentially elastic moduli measure the relationship between the stress applied to a tissue and the deformation that occurs in response to that stress.…”

Peripheral nerve disorders are commonly encountered in clinical practice. Electrodiagnostic studies remain the cornerstone of the evaluation of nerve disorders. More recently, ultrasound has played an increasing complementary role in the neuromuscular clinic. Ultrasound elastography is a technique that measures the elastic properties of tissues. Given the histological changes that occur in diseased peripheral nerves, nerve ultrasound elastography has been explored as a noninvasive way to evaluate changes in nerve tissue composition. Studies to date suggest that nerve stiffness tends to increase in the setting of peripheral neuropathy, regardless of etiology, consistent with loss of more compliant myelin, and replacement with connective tissue. The aim of this systematic review is to summarize the current literature on the use of ultrasound elastography in the evaluation of peripheral neuropathy. Limitations of ultrasound elastography and gaps in current literature are discussed, and prospects for future clinical and research applications are raised.

Background There is emerging evidence that ultrasound elastography may provide additional diagnostic information in peripheral neuropathies. Objective To investigate the use of ultrasound elastography to evaluate median nerve stiffness in patients with carpal tunnel syndrome (CTS), as well as the relationship between the elastographic stiffness and electrophysiological severity. Design Case control study. Setting Tertiary hospital outpatient neurophysiology clinic. Participants Twenty eight patients (47 wrists) with CTS and 25 control patients (25 wrists). Interventions None. Main Outcome Meaures Ultrasound parameters (median nerve cross‐sectional area [CSA] at carpal tunnel, ratio of median nerve CSA at carpal tunnel and forearm), shearwave elastography parameter (median nerve stiffness), and electrophysiological severity of carpal tunnel syndrome. Results In patients with CTS, median nerve stiffness by ultrasound elastography was increased between the different severity groups (control 83.5 ± 24.8, EDx negative CTS 84.2 ± 46.4, mild 117.7 ± 79.3, moderate 144.0 ± 71.1, severe 196.6 ± 48.4). The control versus moderate and severe subgroup was statistically significant. Conclusions In total, this study has demonstrated that ultrasound elastography was able to discriminate the severity of CTS whereas conventional ultrasound parameters did not.
