Methods Twenty-six tendons of 24 patients nine men 15 women mean age SD 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. Results With CEUS a significantly greater extent of vascularity could be detected than by using PDUS P . In terms of peri- and intratendinous vessels CEUS was significantly more sensitive in the detection of vascularization compared with PDUS P . No significant correlation between synovial thickening and extent of vascularity could be found P to . Interobserver reliability was calculated to be excellent when evaluating the grading score k to . Conclusions CEUS is a promising tool to detect tendon vascularity with higher sensitivity than PDUS by improved detection of intra- and peritendinous vascularity. Introduction Besides mechanical overloading and attrition rheumato-logic diseases are widespread causes of tenosynovitis and tendinosis. These chronic systemic
