Core Tip

Core tip: As a feature of ultrasonography, high resolution shows the presence of deposits and defines their locations in the tendon, plus their size and texture. This technique enables staging of the deposits by correlation of shadow cones. In the resting phase, the deposits appear hyperechoic and arc shaped, whereas they appear non-arc shaped (fragmented/punctate and cystic) in the resolving phase. These appearances can also be correlated with the symptomatic and asymptomatic phases of the disease.
