Both magnetic resonance imaging and ultrasonography of the wrist have been advocated for the diagnosis of occult dorsal carpal ganglia. This clinical series compares the utility of the two techniques for confirming clinical suspicion of such occult ganglia. Four wrists in three patients with suspected occult dorsal ganglia were identified prospectively over a 12-month period. Each patient underwent imaging with both techniques on the same day. Subsequently, the wrist was operatively explored and the excised tissue was microscopically evaluated. All wrists in this series had positive magnetic resonance imaging and ultrasound findings, with operative and histologic confirmation of the diagnosis. No diagnostic advantage of one imaging study over the other was identified. With its lower cost and lack of contraindications, ultrasound may be the more suitable technique for establishing the diagnosis of occult dorsal carpal ganglion when clinical findings are inconclusive.
磁共振成像和手腕超声检查都被推荐用于隐匿性背侧腕管囊肿的诊断。本临床系列比较了这两种技术在证实此类隐匿性囊肿临床怀疑方面的效用。在12个月期间前瞻性地确定了3例疑似隐匿性背侧囊肿患者的4只手腕。每位患者在同一天接受了两种技术的成像检查。随后，对手腕进行手术探查，并对切除的组织进行显微镜评估。本系列所有手腕的磁共振成像和超声检查结果均为阳性，手术和组织学确诊。未发现一种影像学检查相对于另一种检查有诊断优势。由于超声成本较低且无禁忌证，当临床检查结果不明确时，超声可能是用于诊断隐匿性背侧腕管囊肿更合适的技术。
