To determine which sonographic appearance of the distal biceps brachii tendon (DBBT) is preferred by readers, and if images obtained by two different operators are reproducible.
We performed an IRB-approved prospective sonographic evaluation of the DBBT in 50 healthy elbows using four different approaches (anterior, lateral, medial, posterior) performed by two operators. Five musculoskeletal radiologists independently reviewed the images, and ranked the four approaches based on overall appearance of echogenicity of the tendon, visualized length, and visualization of the insertion.
The medial approach was preferred in 79.6% of elbows, anterior in 17.6%, lateral in 2.8%, and the posterior approach was never preferred. The difference was statistically significant (P < 0.001). Kappa values for the five readers were 0.61 to 0.8 for choosing the images produced by the medial approach.
The appearance of the DBBT using the medial approach is preferred by readers and is reproducible between different operators.
确定读者更喜欢哪种肱二头肌长头肌腱（DBBT）的远端超声表现，以及由两名不同操作者获得的图像是否具有可重复性。
我们对 50 例健康肘部进行了 IRB 批准的前瞻性超声评估，使用两种操作者进行的四种不同方法（前、侧、内、后）。五名肌肉骨骼放射科医生独立查看图像，并根据肌腱的回声均匀性、可显示长度和插入部位的可视化程度对四种方法进行总体外观评分。
79.6%的肘部首选内侧入路，17.6%的肘部首选前侧入路，2.8%的肘部首选外侧入路，而没有任何一个肘部首选后侧入路。差异具有统计学意义（P<0.001）。对于选择内侧入路图像，五位读者的 Kappa 值为 0.61 至 0.8。
内侧入路显示的 DBBT 外观更受读者欢迎，并且在不同操作者之间具有可重复性。
