To evaluate the usefulness of ultrasound (US) and magnetic resonance (MR) imaging in patients suspected of having an occult dorsal carpal ganglion.
The authors prospectively studied US and MR images of 14 wrists in 13 consecutive patients suspected of having an occult dorsal carpal ganglion.
Eleven dorsal carpal ganglia were identified with US and nine with MR imaging. One patient refused the MR imaging study. Of two equivocal cases at MR imaging, one was a ganglion and another was a compressible capsular recess, as determined at US. One ganglion was missed with both techniques. The average diameter of the ganglion cysts was 4.9 mm.
MR imaging and US are equally effective in the detection of occult dorsal carpal ganglia. Because of its dynamic capabilities and lower cost, US should be the initial imaging procedure for suspected occult dorsal carpal ganglia.
评估超声（US）和磁共振（MR）成像在疑似隐匿性腕背侧腱鞘囊肿患者中的应用价值。
作者前瞻性地研究了连续13例疑似隐匿性腕背侧腱鞘囊肿患者的14只手腕的超声和磁共振图像。
超声检查发现11个腕背侧腱鞘囊肿，磁共振成像发现9个。1例患者拒绝磁共振成像检查。在磁共振成像的2例可疑病例中，1例经超声检查确定为腱鞘囊肿，另1例为可压缩的关节囊隐窝。两种检查方法均漏诊1个腱鞘囊肿。腱鞘囊肿的平均直径为4.9毫米。
磁共振成像和超声在检测隐匿性腕背侧腱鞘囊肿方面同样有效。由于超声具有动态观察能力且成本较低，对于疑似隐匿性腕背侧腱鞘囊肿的患者，超声应作为初始成像检查方法。
