A prospective study was performed on 28 patients who underwent surgery for tendon disorders around the ankle. Preoperatively, all patients had real-time, high resolution ultrasonography performed with a 7.5 or 10 mHz transducer. Twenty of these patients also had a preoperative magnetic resonance imaging (MRI) examination of the ankle. A total of 54 tendons were inspected intraoperatively, revealing a total of 24 intrasubstance or complete tendon tears. These surgical findings were compared with the ultrasound and MRI findings, from which the sensitivity, specificity, and accuracy were calculated for both modalities. Ultrasound produced results with a sensitivity measurement of 100%, specificity of 89.9%, and accuracy of 94.4%. MRI produced results with a sensitivity measurement of 23.4%, specificity of 100%, and accuracy of 65.75%. Ultrasound results were more sensitive and accurate than MRI in the detection of ankle tendon tears in our study.
对28例接受踝关节周围肌腱疾病手术的患者进行了一项前瞻性研究。术前，所有患者均使用7.5或10兆赫兹的换能器进行实时高分辨率超声检查。其中20例患者还进行了踝关节术前磁共振成像（MRI）检查。术中共检查了54条肌腱，发现共有24条肌腱实质内或完全撕裂。将这些手术结果与超声和MRI结果进行比较，计算出两种检查方式的敏感性、特异性和准确性。超声检查结果的敏感性为100%，特异性为89.9%，准确性为94.4%。MRI检查结果的敏感性为23.4%，特异性为100%，准确性为65.75%。在我们的研究中，超声在检测踝关节肌腱撕裂方面比MRI更敏感、更准确。
