“…We found near-perfect interreader reliability (. 0.89), similar to indings of other investigators (20)(21)(22). Despite this, the limits of agreement were wide; for velocity, 95% of measurements were expected to lie within 20.74 and +0.86 m/sec of each other, when the mean measurement was approximately 2 m/sec.…”

To examine if shear-wave elastography (SWE) improves the accuracy of diagnosing soft-tissue masses as benign or malignant compared with US alone or in combination with MRI. Materials and Methods: Two hundred six consecutive adult participants (mean age, 57.7 years; range, 18-91 years), including 89 men (median age, 56.0 years; range, 21-91 years) and 117 women (median age, 59.1 years; range, 18-88 years), who were referred for biopsy of a soft-tissue mass were prospectively recruited from December 2015 through March 2017. Participants underwent B-mode US, MRI, and SWE prior to biopsy. hree musculoskeletal radiologists independently reviewed US images alone, followed by US and MRI images together, and classiied lesions as benign, probably benign, probably malignant, or malignant. For SWE, the area under the receiver operating characteristic (ROC) curve (AUC) was calculated for transverse shear-wave velocity (SWV). Multivariable logistic regression was used to investigate the association between SWE and malignancy alongside individual demographic and imaging variables. Results: At histologic examination, 79 of 206 (38%) participants had malignant lesions. SWV showed good diagnostic accuracy for lesions classiied as benign or probably benign by US alone (AUC = 0.87 [95% conidence interval {CI}: 0.79, 0.95]). SWV did not provide substantive diagnostic information for lesions classiied as probably malignant or malignant, whether the classiication was made with or without MRI. However, multivariable modeling indicated that diagnostic accuracy may vary by lesion position (interaction P = .

“…Obviously, the use of pSWE has some advantages and disadvantages [22,23]; it is a non-invasive cheap method, simple to apply and a more acceptable alternative for patients who have difficulty with magnetic reso- nance imaging that, at the same time, is also more expensive. The ability to see in real time in the monitor a shear wave graph, gives us a prompt feedback on the quality of the measurements, permitting any rapid corrections.…”

Reliability of quantitative point shear-wave ultrasound elastography on vastus medialis muscle and quadriceps and patellar tendons

Aim: The aim of this work was to evaluate the reliability of pSWE in assessing the stiffness of the vastus medialis muscle and of the quadriceps and patellar tendons.Material and methods: For this purpose, 18 subjects (9 males and 9 females of 57±22 years) in good clinical conditions were included in this study. pSWE examination was conducted by a unique expert operator with more than ten years of experience in musculoskeletal ultrasound. Two sets of five measurements for each muscle and tendon district were bilaterally performed at the same manner, at least fifteen minutes apart. The mean value of the measurements of each set was statistically compared with that of the other set.Results: No significant differences were found comparing the mean value of the measurements of the two sets of evaluation performed in muscle and tendon areas (vastus medialis muscle: p=0.285; quadriceps tendon: p=0.979; patellar tendon: p=0.187). The intraclass correlation coefficient was excellent for all areas (vastus medialis muscle: 0.969; quadriceps and patellar tendons: 0.995 and 0.989, respectively).Conclusion: The pSWE technique demonstrated that it was a reliable method for measuring stiffness in vastus medialis muscle and quadriceps and patellar tendon in subjects who had undergone orthopedic surgery. This opens the possibility of many applications in monitoring stiffness before and after surgery and during rehabilitation.

“…This method of SWE measurement has been shown to be highly reliable for the supraspinatus muscle and tendon. 23,32,33 Moreover, a previous study evaluating between-day experiments demonstrated good temporal reliability of SWE measurements. 34 For the supraspinatus tendon, the ultrasound probe was aligned with the tendon fibers, 35 and the repaired tendon was imaged at the site of anteromedial anchor insertion.…”

Re‐tearing after arthroscopic rotator cuff repair (ARCR) frequently occurs, and high stiffness of the rotator cuff may be one of the factors. We investigated changes in stiffness of the supraspinatus muscle and tendon after ARCR as measured by shear wave elastography (SWE) with B‐mode ultrasound, and compared the supraspinatus muscle stiffness of patients with recurrent tears and patients with healed rotator cuffs. Sixty patients with supraspinatus tears requiring ARCR underwent serial SWE of their supraspinatus muscles and repaired tendons. SWE was performed before surgery (Pre‐Op) and at 1 week, 1 month, 2 months, 3 months, 4 months, 5 months, and 6 months after surgery. Additionally, the repaired rotator cuffs were evaluated using magnetic resonance imaging at 6 months after surgery to classify patients into a healed rotator cuff group and a recurrent tear group. Differences in SWE values between the groups were assessed at each time point. The SWE value of the repaired tendon at 1 week after ARCR was significantly greater than at 3 and 6 months. The SWE value for the supraspinatus muscle at 1 month after ARCR surgery in the healed group was lower than at Pre‐Op and 4, 5, and 6 months after surgery, and it was also lower than that at 1 month after surgery in the re‐tear group. There were no significant differences between time points in the SWE values of the supraspinatus muscle in the re‐tear group. The SWE value of the muscle in the re‐tear group was greater than in the healed group at 1 month after surgery (p < 0.05). Increased SWE values at 1 month after ARCR may predict recurrent rotator cuff tears after surgery rather than evaluating the tendon. © 2019 Orthopaedic Research Society.
