Figure Lengend Snippet: SWE of the right elbow in the same 49-year-old man with chronic lateral tendinopathy. a Baseline long-axis SWE of the common extensor tendon and radial collateral ligament complex shows the ROI. b Corresponding VTIQ parametric velocity map with three equidistant ROI placed within the tendon, aligned from the apex to the base of the epicondyle to measure the local SWVs. The mean SWV was 5.55 m/s. c At the 6-month follow-up exam, the mean SWV was 8.29 m/s. d At the 12-month follow-up exam, the mean SWV was 9.15 m/s
Article Snippet: The entire tendon was scanned, capturing the area with the highest neovessel density. a Baseline long-axis US with Power Doppler imaging reveals pixels of Doppler signal covering around 50% of the tendon surface, indicating Grade 2 neovascularity. b Following tendon fenestration treatment, the 6-month follow-up long-axis US displays partial neovessel regression, with a few pixels of Doppler signal indicating Grade 1 neovascularity. c The 12-month follow-up long-axis US exhibits a nearly complete resolution of the Doppler signal (Grade 1 neovascularity) Using Siemens’s virtual touch tissue imaging and quantification (VTIQ) software, we assessed SWV on a long-axis image depicting the minor groove at the base of the lateral humeral epicondyle.
