The accuracy of sonoelastography in fatty degeneration of the supraspinatus: a comparison of magnetic resonance imaging and conventional ultrasonography

Abstract

SE is valuable in the quantitative assessment of the severity of the fatty atrophy of the supraspinatus and has an excellent accuracy, an excellent correlation with MRI and the conventional US, and an excellent interobserver reliability.

Ultrasound elastography: compression elastography and shear-wave elastography in the assessment of tendon injury

“… USE in combination with conventional US provided improved sensitivity ( p < 0.02) without loss of specificity and had correlation with histology evaluation ( κ = 0.78, p < 0.02). Rotator cuff tendons Seo et al 2014 [ 45 ] 98 patients/101 shoulders with lesions (cuff tears, tendinopathies, adhesive capsulitis, calcific tendinitis, labral lesions). Cross-sectional.…”

“…This makes USE particularly interesting when conventional US cannot differentiate between healthy and pathological tissue. The findings on USE were correlated to magnetic resonance imaging (MRI) [ 45 , 46 , 49 , 62 ] and conventional US [ 45 , 46 , 60 ]. Rosskopf et al demonstrated that V s decreased with increasing fat content and supraspinatus muscle atrophy, and was increased in the final stage of fatty infiltration [ 58 ].…”

Ultrasound Elastography in Musculoskeletal Radiology: Past, Present, and Future

“…26 Two other important sites in USE tendon research are the rotator cuff and the common extensor and flexor tendons of the elbow. [52][53][54] In Achilles tendinopathy evaluation, the studies showed moderate to perfect correlation between the USE and Bmode US and excellent correlation with functional scores. 54,55 Coombes et al reported that low shear wave velocity is correlated with higher age, self-reported pain, and with decreased loading capacity of the Achilles tendon.…”

“…55 Correlation between USE and Bmode US in the evaluation of rotator cuff was reported. 52,53 Rosskopf et al showed decreased shear wave velocity with increasing fat content and increasing shear wave velocity in the final stage of fatty infiltration of the supraspinatus muscle. 52 Seo et al reported that USE is able to quantify the severity of fatty atrophy of the supraspinatus muscle with excellent accuracy and interobserver reliability.…”

“…52 Seo et al reported that USE is able to quantify the severity of fatty atrophy of the supraspinatus muscle with excellent accuracy and interobserver reliability. 53 USE may prove to be useful in the preoperative setting in patient selection because it can reflect tendon quality or surgical outcome. 58 In diagnosing medial epicondylitis, the addition of USE to B-mode US provides a significant improvement in the agreement between imaging and histologic results compared with either B-mode US or USE alone.…”
