Figure 2

(a) Transverse greyscale ultrasound image of an enlarged Achilles tendon, with low reflectivity on its superficial aspect affecting approximately 50% of the anteroposterior diameter of the tendon. (b) Longitudinal ultrasound image with colour Doppler. The tendon is fusiform in morphology, consistent with chronic non-insertional tendinosis, and the superficial aspect of the tendon shows low reflectivity. Moderate (grade 3) vascularity is seen in the tendon.
