Abstract:Achilles tendon is the largest tendon in the human body, which plays an important role in lower limb movements. Achilles tendon diseases include Achilles tendon rupture and Achilles tendinopathy. With the continuous development of new ultrasonic technology, Musculoskeletal ultrasound is widely used in Achilles tendon and provides important reference information for the diagnosis, treatment and follow-up of Achilles tendon diseases.This paper reviews the application progress of conventional ultrasound and ultrasonic elastography (UE), interventional ultrasound, superb microvascular imaging (SMI), contrast-enhanced ultrasonography (CEUS), and three-dimensional imaging in Achilles tendon diseases
