Sonographic examination of the hand requires high-frequency linear transducers. As the relevant structures are located very close to the surface, water stand-off pads are mandatory. Owing to the high sensitivity of sonography in the detection of fluid, exudative synovitis, tenosynovitis and ganglia can be easily diagnosed. Sonographic information on muscle atrophy and alterations of the shape and echogenicity of the median nerve in patients with carpal tunnel syndrome may be useful in evaluating the extent of disease. Further indications for the sonographic examination of the hand include suspected tumors, foreign bodies and synovial proliferation. Osseous destruction can be visualized in patients with rheumatoid disease, but the precise extent is hard to determine.
手部超声检查需要使用高频线性换能器。由于相关结构位于非常靠近体表的位置，必须使用水囊垫。由于超声在检测液体方面具有高灵敏度，渗出性滑膜炎、腱鞘炎和腱鞘囊肿很容易被诊断出来。腕管综合征患者肌肉萎缩以及正中神经形态和回声改变的超声信息，可能有助于评估疾病的严重程度。手部超声检查的其他适应证包括疑似肿瘤、异物和滑膜增生。类风湿性疾病患者的骨质破坏可以通过超声显示，但精确范围难以确定。
