“…Since that initial report, multiple other studies and case reports have built on the premise that increased signal intensity and tendon width was diagnostic for supraspinatus tendinosis. [4][5][6][7]9,10 Recently, the canine supraspinatus tendon has been examined using the indirect visualization methods of MRI and ultrasound and compared with direct histologic evaluation of the intact tissue. 3,14 The MRI displayed a unique tendon insertion as compared with other tendons in that the attachment to the greater tubercle is normally wide with a trilaminar morphology comprised of superficial parallel collagen fibres, a large central collection of haphazardly arranged collagen fibres in abundant tendon matrix and a deep margin of predominantly parallel collagen fibres blending into the joint capsule margin.…”

“…The recent implementation of magnetic resonance imaging (MRI) in veterinary medicine provides a means by which to assess supraspinatus tendon and muscle morphology. [3][4][5][6][7][8][9][10][11][12][13] Early MRI analysis of the supraspinatus tendon structure presupposed that the canine tendon features would display features common to other tendons, 13 specifically highly organized tendon fibres with a corresponding hypointense signal on conventional T1, T2 and proton density spin echo (SE) and fast spin echo (FSE) imaging. Additional presumptions were made that damage or tendon pathology would be identified as hyperintensity and widened tendon margins during the acute phase of injury.…”

Objective The normal canine supraspinatus tendon has properties commonly attributed to damage such as core hyperintensity and increased width. Little is published regarding the normal tendon, including how senescent changes and sex differences may affect the appearance. Conventional magnetic resonance imaging (MRI) techniques provide subjective analysis of tendons based on observer assessment of signal intensity and appearance. Quantitative MRI (qMRI) techniques such as T2 mapping provide an objective comparison of collagen orientation with analysis of a decay constant, T2. This study investigates age and sex related changes in the canine supraspinatus tendon using the qMRI technique of T2 mapping. Methods In this study, 34 tendons of clinically sound male and female dogs (0.6–13 years) were imaged using qMRI T2 mapping techniques. Sagittal plane T2 maps of the supraspinatus tendon were depth-normalized, and profiles compared using two separate four-parameter logistic equations describing T2 mapping profiles as sigmoidal curves. Combined parameters evaluated included range of T2 values, curve steepness, vertical curve shift, lower bound of T2, upper bound of T2 and horizontal curve shift. Results A significant reduction in the most central portion of the supraspinatus tendon was found for every increased year in age (−1.56 ± 0.47 milliseconds [−2.56, −0.56, p = 0.004]). No significant difference in curve parameters was found between sexes. Conclusion The reduction in T2 with age suggests a senescent change may be anticipated with the canine supraspinatus tendon.

“…After treatment, the symptoms of supraspinatus tendinitis are usually relieved, but its recurrence is common, which affects the patient’s life quality and leads to calcium or other pathological changes[ 6 ]. One of the main reasons for the high probability of recurrence is the lack of objective curative measures[ 7 ]. At present, the visual analogue scale (VAS) and Constant-Murley score (CMS) are often utilized to evaluate the pain and function of the shoulder and to judge the effect of treatment[ 8 , 9 ].…”

“…Although magnetic resonance imaging is the most accurate tool in the diagnosis of supraspinatus tendinitis, it is not suitable for the evaluation of treatment efficacy because frequent assessment is unrealistic[ 7 ]. With the expansion of ultrasound applications, musculoskeletal ultrasound is increasingly popular.…”

BACKGROUND Supraspinatus tendinitis recurs easily after treatment. One of the main reasons is the lack of objective tools for the efficacy evaluation. Shear wave elastography (SWE) can quantitatively analyze the tissue elasticity of region of interest by measuring the Young’s modulus (YM) value. AIM To explore the role of SWE in the efficacy and prognostic evaluation of supraspinatus tendinitis. METHODS Eighty-seven patients with supraspinatus tendinitis treated in Jiading District Central Hospital Affiliated Shanghai University of Medicine and Health Sciences were recruited. Another 30 healthy volunteers were enrolled as the control group. The visual analogue scale (VAS) and Constant-Murley Score (CMS) were recorded before treatment. All participants were scanned by SWE scan, and the YM value of the region of interest were recorded. Spearman correlation analysis was performed on YM values with VAS and CMS. Univariate repeated measures analysis of variance was used to calculate the changing trend of VAS, CMS and SWE under different treatment courses. After treatment, the patients were further grouped based on who achieved significantly effective and curative treatment. The patients in the continued treatment group continued to receive treatment according to the YM value, and the remaining patients who stopped receiving treatment were included in the stopped treatment group. All patients were followed up for 1 year, and the difference in recurrence rates between the continued treatment group and the stopped treatment group were compared. RESULTS The SWE images of supraspinatus muscle in healthy volunteers were mainly blue, while those of patients with supraspinatus tendinitis showed regional red and green areas. The average YM value of the supraspinatus muscle in healthy volunteers was 26.12 ± 4.03 kPa. The average YM value of patients with supraspinatus muscle was greater than that of healthy volunteers (average YM = 60.61 ± 11.53 kPa, t = 26.344, P < 0.001). The YM value was positively correlated with VAS ( r = 0.564, P < 0.001) and negatively correlated with CMS ( r = -0.411, P < 0.001). The changes of VAS and CMS were the most obvious in course 1 and then decreased gradually. The degree of change in YM values was similar in different courses. After a 1-year follow-up, the cumulative relapse-free rate in the continued treatment group was 91.43%, which was significantly higher than that in the stopped treatment group (64.71%, X 2 = 7.379, P = 0.007). CONCLUSION SWE can objectively indicate the severity of supraspinatus tendinitis. Using the YM value as a criterion for curative effect may reduce the recurrence rate.
