Fourteen patients with chronic dorsal wrist pain of unknown etiology underwent high-resolution magnetic resonance imaging (MRI) examination formatted to evaluate the scapholunate interval. Ten had MRI evidence that was diagnostic for an occult dorsal wrist ganglion. The average measured 4.7 mm at greatest diameter. Eight of 10 patients had the diagnosis confirmed, 7 at the time of surgery, and 1 at follow-up examination when the ganglion enlarged and was no longer occult. The other two opted for nonoperative management. The positive predictive value of a positive MRI finding for occult dorsal wrist ganglion was 100% in this small series. The use of a properly formatted high-resolution MRI in this patient population was diagnostic for occult dorsal wrist ganglion.
14例病因不明的慢性腕背疼痛患者接受了高分辨率磁共振成像（MRI）检查，成像格式用于评估舟月间隙。10例患者的MRI证据可诊断为隐匿性腕背腱鞘囊肿。最大直径平均测量值为4.7毫米。10例患者中有8例确诊，7例在手术时确诊，1例在随访检查时确诊，此时腱鞘囊肿增大且不再隐匿。另外2例选择非手术治疗。在这个小样本系列中，MRI检查结果阳性对隐匿性腕背腱鞘囊肿的阳性预测值为100%。在该患者群体中，使用格式正确的高分辨率MRI可诊断隐匿性腕背腱鞘囊肿。
