“…The best cine-image derived from at least three compression-relaxation cycles was used for the assessment of SE. We have used color-scales and strain ratios for the description of elastographic findings which is defined in the literature [18,20]. In this method, blue and green colors represented hard, whereas yellow and red colors represented intermediate and severely soft tendons, respectively.…”

Aims: Tendons are crucial for optimal muscle force transfer and subject to changes with aging which may impair functional ability of elderly individuals. Achilles is the largest and the strongest tendon in the body; therefore it is an excellent site for the radiologic investigation of aging of tendons. Sonoelastography (SE) is a new ultrasound-based imaging technique that provides information on elastic properties and stiffness of tissues. The aim of our study was to investigate the age-related alterations in Achilles tendons using SE. Material and methods: Forty five geriatric (age≥ 65 years) and 42 young (age 18-40 years) healthy consecutive subjects were enrolled. Subjects with known history of metabolic or endocrine diseases, sports or traumatic injuries, peripheral vascular disorders were excluded. Both Achilles tendons were scanned with a real-time SE probe at a frequency of 6-15 MHz. Strains of Achilles tendons' proximal, middle and distal parts were assessed semi-quantitatively with comparing a reference tissue. Results: Both SE methods -color coded evaluation and strain measurement-showed a remarkably stiffer tendon in the elderly subjects compared to young subjects in all thirds of Achilles tendons. In young subjects 84.9 % tendon thirds were blue, and 15.1% were green whereas, in elders 93.7% were blue and 6.3% were green (p=0.024). There was a significant correlation between age and stiffness of tendons assessed with strain indices. Conclusion: Our result showed increased tendon stiffness in elderly subjects which might be responsible for the high prevalence of Achilles tendinopathies observed in elderly subjects.

“…The strain ratio was calculated by comparing the Achilles tendon to the adjacent fat tissue. The first region of interest (ROI)(A) was placed in the fat tissue as a reference tissue and, the other ROIs(B) were placed in each part of the Achilles tendon [20]. The strain ratio (B/A) was automatically calculated by the sonography machine.…”

“…On the opposite side, diabetic patients with foot ulcers had thicker but softer tendons than healthy controls and diabetic patients without foot ulcers 41. In patients affected by ankylosing spondylitis, tendon pain was higher in patients with areas of softening. In particular, the distal third was the most commonly affected site and it was commonly associated with both bone erosion and enthesis enlargement 15,42 . Onal et al reported that patients with acromegaly had thicker tendon than healthy subjects, especially in active phase of disease.…”

SummaryBackground: Sonoelastography (SE) is a new ultrasound-based method adopted in an increased number of scientific reports to analyse normal and pathological tendons. The aim of this study is to provide a systematic overview of clinical applications of SE in normal and pathological tendons. Methods: A systematic research of PubMed, Ovid, and Cochrane Library electronic databases was performed according to PRISMA guideline. Two Authors searched and evaluated the articles independently; a third Author was involved to solve any disagreement. The Oxford Level of Evidence (LoE) was used to assess each article. Results. There is an increasing interest in the application of SE in the evaluation of healthy and diseased tendons. Many different tendons are amenable for SE evaluation, such as the Achilles and patellar tendons, rotator cuff, common extensor tendons, quadriceps tendon, and the plantar fascia.Conclusion. SE appears to be a very useful diagnostic tool, in particular in tendon pathology. This is a dynamic examination, provides an immediate evaluation of the tissue elasticity, and may be useful in recognizing tendon abnormalities and in implementing the information available with conventional US. Level of evidence: IV.
