“…These histopathologic alterations of tendinopathy have been found to increase the compressibility of tissue on ultrasound scans and may cause softening of the tissue on SE [33]. De Zordo et al reported that SE is valuable in the detection of intratendinous and peritendinous alterations in lateral epicondylitis or Achilles tendinopathy [23,34]. In this study, distinct focal lesions were detected with SE and scored as grade 0 in 7.6 % of cases, grade 1 in 30.5 %, grade 2 in 19.5 %, and grade 3 in 42.4 %.…”

Background and purpose Sonoelastography (SE) is a new technique that can assess differences in tissue stiffness. This study investigated the performance of SE for the differentiation of supraspinatus (SSP) tendon alterations of tendinopathy compared to magnetic resonance imaging (MRI) and conventional ultrasonography (US). Methods One hundred and eighteen consecutively registered patients with symptoms and MRI findings of SSP tendinopathy were assessed with US and SE. Coronal images of the SSP tendon were obtained using US and SE. Increased signal intensity on T2-weighted images in the coronal planes were graded according to the extent of the signal changes from ventral to dorsal. SE images were evaluated by reviewers using an experimentally proven color grading system. Results Using SE, 7.6 % of the SSP tendons were categorized as grade 0, 30.5 % as grade 1, 19.5 % as grade 2, and 42.4 % as grade 3. Evaluation of the interobserver reliability of the SE findings showed ''almost perfect agreement'', with a weighted kappa coefficient of 0.83. By comparing the MRI findings with the SE findings, grades of MRI and SE had a positive correlation (r = 0.829, p = \0.001). Furthermore, grades of US and SE also had a positive correlation (r = 0.723, p = \0.001). Conclusions SE is valuable in the detection of the intratendinous and peritendinous alterations of the SSP tendon and has excellent interobserver reliability and excellent correlation with MRI findings and conventional ultrasonography findings.Keywords Rotator cuff Á Tendinopathy Á Ultrasonography Á Sonoelastography Riassunto Obiettivi La sonoelastografia (SE) è una nuova tecnica in grado di valutare le differenze di rigidità dei tessuti. Questo studio ha valutato le capacità della SE nella differenziazione delle alterazioni tendinee da tendinopatia del sovraspinato (SSP) rispetto a risonanza magnetica (MRI) ed ecografia convenzionale (US). Materiali e Metodi Centoventuno pazienti con sintomi e reperti MRI di tendinopatia del SSP sono stati valutati con US e SE. Si sono realizzate immagini coronali del tendine SSP utilizzando US e SE. Sono state valutate immagini T2-pesate, per la maggiore intensità del segnale, nei piani coronali, da ventrale a dorsale. Immagini di SE sono state valutate da revisori che utilizzavano un sistema di grading di colore sperimentale. Risultati Utilizzando la SE, 7,4 % dei tendini SSP sono stati classificati come di grado 0, 29,8 % di grado 1, 19,8 % di grado 2, e 43,0 % di grado 3. La valutazione inter-osservatori dei risultati SE ha mostrato ''accordo quasi perfetto'', con un coefficiente kappa pesato di 0,83. Confrontando i risultati della risonanza magnetica con i risultati della SE, risonanza magnetica e SE hanno avuto una correlazione positiva (r = 0,849, p = \ 0.001). Inoltre, anche US e SE hanno avuto una correlazione positiva (r = 0,706, p = \ 0,001). Conclusioni La SE è valida nella rilevazione delle alterazioni intra-tendinee e peri-tendinee del tendine SSP e ha un'ottima affidabilità inter-osservatori e un'eccellente ...

Aims: To describe the sonoelastographic appearance of the Achilles tendon in acromegalic patients and to determine whether the blood concentrations of growth hormone (GH) and insulin-like growth factor (IGF-1) are associated with the various sonographic elasticity types of Achilles tendons. Material and methods: Eighty-four Achilles tendons of 42 acromegaly patients and 84 Achilles tendons of 42 healthy volunteers were assessed with sonoelastography.

“…Sonoelastographic grading was performed on the basis of cine loops of the compression-relaxation cycle to ensure reproducible results. We concentrated on the middle of each cycle, since the most reliable results are provided during this phase (15). In addition, the position of B-mode US and sonoelastography are not considered 100% comparable.…”
