摘要:

目的 探讨黏弹性成像(STVi)与剪切波弹性成像(SWE)对乳腺结节良恶性的鉴别诊断价值。 方法 前瞻性收集2024年10月至2025年2月于滨州医学院附属医院就诊的患者102例104个乳腺结节(良性组52个,恶性组52个),均经手术或空心针穿刺活检病理确诊,使用迈瑞昆仑Resona A20S超声设备获取结节内部及周围2 mm组织的黏性系数和杨氏模量,并分析各自的诊断效能以及弹性参数值与结节最大径的相关性、两参数间相对应的相关性。 结果 恶性结节组的弹性参数值 [结节内部最大黏性系数(Vimax):5.93(4.33,8.47)Pa·s、最大杨氏模量(Emax):81.18(58.31,120.33)kPa;结节周围2 mm组织的最大黏性系数(Vi2max):7.57(5.40,10.16)Pa·s、最大杨氏模量(E2max):117.21(65.66,170.66)kPa]显著高于良性结节组[Vimax:3.70(2.69,5.32)Pa·s、Emax:41.42(28.29,64.25)kPa;Vi2max:4.30(3.63,5.65)Pa·s、E2max:47.23(36.42,74.67)kPa](P < 0.05)。结节周围2 mm组织的诊断效能(Vi2max:0.78、E2max:0.81)优于结节内部(Vimax:0.72、Emax:0.77)的诊断效能(P < 0.05)。联合诊断(Vi2+E2、Vi+E)的AUC值为0.82、0.77,高于单独应用STVi的诊断效能(P < 0.05),虽然略高于SWE的诊断效能,但差异并无统计学意义(P > 0.05);结节最大径与弹性参数最大值具有一定的相关性,其中E2max与结节最大径的相关性最强(r = 0.510,P < 0.05)。 结论 STVi和SWE对于乳腺结节良恶性的鉴别均有一定的临床应用价值,值得注意的是,基于结节周围2 mm组织的弹性参数值,其鉴别效能优于结节内部区域,二者联合可以提高STVi的诊断效能。

Abstract:

Objective To evaluate the diagnostic efficacy of sound touch viscoelastography (STVi) and shear wave elastography (SWE) in distinguishing between benign and malignant breast nodules. Methods A total of 104 breast nodules (52 benign and 52 malignant) from 102 patients scheduled for surgical treatment at Binzhou Medical University Hospital between October 2024 and February 2025 were prospectively enrolled. All nodules were pathologically confirmed through surgical excision or core needle biopsy. The viscosity coefficient and Young′s modulus of both intranodular and perinodular tissues within a 2-mm range were measured using the Mindray Resona A20S ultrasound system. The diagnostic performance of each parameter, the correlation between elastic parameter values and the maximum nodule diameter, as well as the inter-correlation between the two parameters were systematically analyzed. Results The elasticity parameters were significantly higher in malignant nodules [maximum intranodular Viscosity coefficient (Vimax): 5.93 (4.33, 8.47) Pa·s, maximum Young′s modulus (Emax): 81.18 (58.31, 120.33) kPa; maximum Viscosity coefficient of the surrounding 2-mm tissue (Vi2max): 7.57 (5.40, 10.16) Pa·s, maximum Young's modulus (E2max): 117.21 (65.66, 170.66) kPa] compared to benign nodules [Vimax: 3.70 (2.69, 5.32) Pa·s, Emax: 41.42 (28.29, 64.25) kPa; Vi2max: 4.30 (3.63, 5.65) Pa·s, E2max: 47.23 (36.42, 74.67) kPa] (P < 0.05). The diagnostic performance of the 2-mm perinodular tissue (Vi2max: 0.78, E2max: 0.81) surpassed that of intranodular tissue (Vimax: 0.72, Emax: 0.77) (P < 0.05). The combined diagnostic model (Vi2+E2,Vi+E) achieved AUC values of 0.82 and 0.77, respectively, which outperformed STVi alone (P < 0.05) and showed marginally better performance than SWE alone, although the difference was not statistically significant (P > 0.05). The maximum nodule diameter showed a moderate correlation with the elasticity parameters, with E2max exhibiting the strongest correlation (r = 0.510,P < 0.05). Conclusions Both STVi and SWE show clinical value in distinguishing between benign and malignant breast nodules. Particularly, elasticity parameters obtained from the 2-mm perinodular tissue demonstrate better diagnostic performance than those measured within the nodule itself, and combining these parameters enhances the overall diagnostic accuracy of STVi.
