BACKGROUND
Previous studies have demonstrated that morphological changes in the suprascapular notch are closely associated with suprascapular nerve entrapment syndrome (SNES). Thus, we hypothesized that the suprascapular notch cross-sectional area (SSNCSA) could be a good diagnostic parameter to assess SNES.
METHODS
We acquired suprascapular notch data from 10 patients with SNES and 10 healthy individuals who had undergone shoulder magnetic resonance imaging (S-MRI) and had no evidence of SNES. T2-weighted coronal magnetic resonance images were acquired from the shoulder. We analyzed the SSNCSA at the shoulder on S-MRI using our image-analysis program (INFINITT PACS). The SSNCSA was measured as the suprascapular notch, which was the most affected site in coronal S-MRI images.
RESULTS
The mean SSNCSA was 64.50 ± 8.93 mm2 in the control group and 44.94 ± 10.40 mm2 in the SNES group. Patients with SNES had significantly lower SSNCSA (P < 0.01) than those in the control group. Receiver operating curve analysis showed that the best cut-off of the SSNCSA was 57.49 mm2, with 80.0% sensitivity, 80.0% specificity, and an area under the curve of 0.92 (95% CI [0.79, 1.00]).
CONCLUSIONS
The SSNCSA was found to have acceptable diagnostic properties for detecting SNES. We hope that these results will help diagnose SNES objectively.
背景
先前的研究表明，肩胛上切迹的形态变化与肩胛上神经卡压综合征（SNES）密切相关。因此，我们假设肩胛上切迹横截面积（SSNCSA）可以作为评估 SNES 的良好诊断参数。
方法
我们从 10 例 SNES 患者和 10 例健康个体中获得肩胛上切迹数据，这些个体均接受了肩部磁共振成像（S-MRI）检查，且没有 SNES 的证据。从肩部获取 T2 加权冠状磁共振图像。我们使用图像分析程序（INFINITT PACS）分析 S-MRI 上的 SSNCSA。SSNCSA 在冠状 S-MRI 图像中最受影响的肩胛上切迹处进行测量。
结果
对照组的平均 SSNCSA 为 64.50±8.93mm2，SNES 组为 44.94±10.40mm2。SNES 患者的 SSNCSA 明显低于对照组（P<0.01）。受试者工作特征曲线分析显示，SSNCSA 的最佳截断值为 57.49mm2，具有 80.0%的敏感性、80.0%的特异性和 0.92 的曲线下面积（95%置信区间 [0.79, 1.00]）。
结论
SSNCSA 被发现具有可接受的诊断 SNES 的特性。我们希望这些结果将有助于客观地诊断 SNES。
