Objective The purpose of this study was to determine the feasibility and the value of percutaneous ultrasound-guided subacromial bursography (PUSB) with contrast-enhanced ultrasound (CEUS) for assessment of rotator cuff tears. Methods Between January 2012 and September 2014, 2-D US and PUSB were prospectively performed in 135 patients with suspected rotator cuff tears from among 2,169 patients with clinically diagnosed subacromial impingement syndrome. Sixty-three patients who had undergone arthroscopy were included. The PUSB findings were compared with those from 2-D US using the McNemar test, with arthroscopy as a standard. Results Of a total of 19 full-thickness tears (FTTs), 2-D US correctly diagnosed 12 and PUSB correctly diagnosed 18 (P--.031). With regard to partial-thickness tears, 2-D US correctly diagnosed 31 and PUSB 35 of a total of 41 tears (P--.375).Accuracy in diagnosing FTTs was 81.0?% for 2-D US and 98.4?% for PUSB. 2-D US and PUSB yielded sensitivity of 63.2?% and 94.7?%, respectively, for full-thickness tears, with specificity of 88.6?% and 100.0?%, respectively. Conclusions PUSB is a safe and feasible procedure, with greater sensitivity and specificity than 2D US in diagnosing FTTs As such, PUSB improves the value of ultrasound for assessing rotator cuff pathology. Key Points -PUSB allows new application of CEUS and offers a new form of bursography. -PUSB appears to facilitate diagnosis of full -thickness rotator cuff tears. -PUSB outlines the rotator cuff tears more clearly than 2-D US.
