【摘要】：目的探讨超声弹性成像技术对腱鞘巨细胞瘤的辅助诊断价值。方法选择因手部肿物于我科检查的102例患者。全部病例均经病理证实。采用弹性成像技术测量弹性适配器与手部肿物的应变比值(SR),应用受试者工作特性曲线评价超声弹性成像对腱鞘巨细胞瘤的诊断价值。结果 (1)传统二维超声诊断腱鞘巨细胞瘤的灵敏度、特异度、准确性、阳性预测值及阴性预测值分别为82.2%、68.4%、74.5%、67.3%、83.0%。(2)应用ROC曲线评价SR诊断腱鞘巨细胞瘤的曲线下面积为0.928,取SR诊断阈值为10.15。(3)利用常规二维超声与超声弹性成像进行联合诊断腱鞘巨细胞瘤时,诊断的灵敏度、特异度、准确性、阳性预测值及阴性预测值分别为91.1%、93.0%、92.2%、91.1%、93.0%。结论超声弹性参数SR对腱鞘巨细胞的诊断有较好的应用价值,常规二维超声与超声弹性成像联合诊断可显著提高诊断效能。
[Abstract]:Objective to evaluate the value of ultrasonic elastography in the diagnosis of giant cell tumor of tendon sheath. Methods 102 patients with hand mass were examined in our department. All cases were confirmed by pathology. The strain ratio of elastic adaptor to hand mass was measured by elastic imaging technique. The diagnostic value of ultrasonic elastic imaging for giant cell tumor of tendon sheath was evaluated by using the operating characteristic curve of the subjects. Results 1) the sensitivity, specificity and accuracy of traditional two-dimensional ultrasonography in the diagnosis of giant cell tumor of tendon sheath. The positive predictive value and the negative predictive value were 82.2 and 74.5and 67.33.0, respectively.) the area under the curve of SR diagnosis of giant cell tumor of tendon sheath was 0.928 by ROC curve, and the diagnostic threshold of SR was 10.15. 3) when using conventional two-dimensional ultrasound and ultrasonic elastic imaging to diagnose giant cell tumor of tendon sheath, The diagnostic sensitivity, specificity, accuracy, positive predictive value and negative predictive value were 91.1 and 93.0, respectively. Conclusion Ultrasonic elastic parameter SR has a good value in the diagnosis of giant cells of tendon sheath. The combined diagnosis of conventional two-dimensional ultrasound and ultrasonic elastic imaging can improve the diagnostic efficiency significantly.
