“…However, we do not have a comparison of CEUS and PDUS in healthy tendons, but in previous studies, using CEUS, entheses are described as nonvascularized areas in healthy controls [17,32]. Furthermore, the peritendinous space within normal tendon sheaths is considered to be nonvascularized [33]. Nevertheless, further studies are required to assess normal tendons regarding potential intratendinous vascularity detectable with CEUS.…”

Detection of vascularity in wrist tenosynovitis: power doppler ultrasound compared with contrast-enhanced grey-scale ultrasound

IntroductionWe sought to assess vascularity in wrist tenosynovitis by using power Doppler ultrasound (PDUS) and to compare detection of intra- and peritendinous vascularity with that of contrast-enhanced grey-scale ultrasound (CEUS).MethodsTwenty-six tendons of 24 patients (nine men, 15 women; mean age ± SD, 54.4 ± 11.8 years) with a clinical diagnosis of tenosynovitis were examined with B-mode ultrasonography, PDUS, and CEUS by using a second-generation contrast agent, SonoVue (Bracco Diagnostics, Milan, Italy) and a low-mechanical-index ultrasound technique. Thickness of synovitis, extent of vascularized pannus, intensity of peritendinous vascularisation, and detection of intratendinous vessels was incorporated in a 3-score grading system (grade 0 to 2). Interobserver variability was calculated.ResultsWith CEUS, a significantly greater extent of vascularity could be detected than by using PDUS (P < 0.001). In terms of peri- and intratendinous vessels, CEUS was significantly more sensitive in the detection of vascularization compared with PDUS (P < 0.001). No significant correlation between synovial thickening and extent of vascularity could be found (P = 0.089 to 0.097). Interobserver reliability was calculated to be excellent when evaluating the grading score (κ = 0.811 to 1.00).ConclusionsCEUS is a promising tool to detect tendon vascularity with higher sensitivity than PDUS by improved detection of intra- and peritendinous vascularity.

“…Because some structures were only visible in larger patients, we hypothesize that the smaller structures may become increasingly difficult to image in smaller patients. High‐frequency probes (>13 MHz) used for examination of musculoskeletal structures of the human extremity 10 may lead to better resolution in smaller dogs.…”

Currently, there are no available anatomic descriptions of the soft tissue structures that are visible with ultrasound in the canine tarsus. Eight cadaver hindlimbs and 10 clinically normal dogs (15-37 kg) were examined with ultrasound to establish which structures could be visualized in normal dogs. The structures always identified included the long digital extensor tendon, the tibialis cranialis tendon, the joint space, and the three bellies of the extensor digitum brevis muscle on the cranial/dorsal aspect of the tarsus. The lateral digital extensor tendon and the peroneus longus tendon were identified as a single structure on the lateral aspect of the tarsus. The caudal/plantar approach allowed identification of the calcaneal tendon, the deep and superficial digital flexor tendons, the plantar ligament, and the lumbricales and interosseus muscles. The medial collateral ligament can be identified on the medial tarsus of larger dogs. This technique has proved useful in the diagnosis of soft tissue injuries of the canine tarsus, and clinical examples of tibialis cranialis tendinopathy, deep digital flexor tendinopathy, fibrosis surrounding the medial collateral ligament and extent of invasion of a tarsal hemangiosarcoma are described.

To evaluate the role of high frequency ultrasonography in diagnosis of acute closed mallet finger injury. 36 patients diagnosed with mallet finger were included in this study. All patients underwent ultrasonography, magnetic resonance imaging(MRI) and X-ray examinations. A new kind of classification of acute mallet finger injury based on ultrasonography findings was described. The difference in terms of extensor tendon injury and bony fragment identification ability among the three types of examinations were described respectively. Either an injury of extensor digital tendon or an avulsion fracture of distal phalangeal base was identified clearly on ultrasonography. Among the 36 cases, avulsion fracture of the distal phalangeal base was found without extensor tendon rupture in Type A, complete rupture of the extensor tendon was found without avulsion fracture in Type B, and contusion of the extensor tendon was found in Type C. Compared with X-ray, ultrasonography and MRI could show the extensor tendon injury clearly. While compared with MRI, ultrasonography and X-ray was more sensitive in showing bony fragment. High frequency ultrasonography could be an accurate, reliable, and non-invasive diagnostic imaging method in diagnosis of acute close mallet finger injury.
