Abstract
Real-time sonoelastography is a new ultrasound-based technique that can provides a non-invasive way to measure tissue mechanical properties in vivo .A compressive force is applied to the tissue surface inducing tissue displacement being less in hard tissue than in soft tissue. Then displacement can be calculated by comparing the echo signal sets obtained before and after compression. The Achilles tendon the largest, thickest and strongest tendon in the human body However, it is the most commonly injured tendon according to several studies. It was the first area to be investigated using free-hand strain sonoelastography. Achilles tendinopathy is a chronic condition that can be diagnosed by ultrasound and MRI. Preliminary studies suggested that the normal Achilles tendon appears as hard structured using EUS, while diseased tendons appeared softer. The aim of this study is to assess the Achilles tendon in healthy volunteers and patients with symptomatic Achilles tendons by using sonoelastography (SEL) and comparing the results to those of conventional ultrasound and MRI findings. This study included 40 healthy volunteer (group I –control group) and 40 patients with symptomatic Achilles tendon (group II). All patients were examined by ultrasound, sonoelastography and MRI. Our results could be summarized in that sonoelastographic evaluation of both studied group showed that Achilles tendon of the volunteer has hard texture with higher strain ratios than that of the patient with Achilles tendinopathy. No significant differences could be detected between Strain.
