摘要

研究目的本研究旨在通过将各种切面弹性成像技术与年龄相结合,优化 BI-RADS 4a 级结节的降级:我们对患者进行了常规超声检查、应变弹性成像(SE)和剪切波弹性成像(SWE)。记录的定量参数包括年龄、横截面积和纵截面积比(C-EI/B、L-EI/B)、应变率比(C-SR、L-SR)、总体平均弹性模量值(C-Emean1、L-Emean1)、五点平均弹性模量值(C-Emean2、L-Emean2)和最大弹性模量值(C-Emax、L-Emax):组织病理学评估显示,在 230 个病灶中,45 个为恶性,185 个为良性。传统超声检查的敏感性和特异性分别为 100%和 0%。相比之下,SE和SWE的特异性较高,但敏感性较低。横断面参数(C-EI/B、C-SR、C-Emean1、C-Emean2 和 C-Emax)优于纵断面参数,其中 C-SR 和 C-Emax 显示出最高的特异性(72.43% 和 73.51%)和令人满意的灵敏度(80.00% 和 88.89%)。将年龄与 C-SR 和 C-Emax 结合使用可显著提高诊断效率,灵敏度达 97.78%,特异度达 77.30%:结论:将年龄与 C-SR 和 C-Emax 结合使用可有效减少大多数 BI-RADS 4a 良性病变的不必要活检,同时保持极低的误诊率。

Combination of Different Sectional Elastography Techniques with Age to Optimize the Downgrading of Breast BI-RAIDS Class 4a Nodules.

Objective: This study aims to optimize the downgrading of BI-RADS class 4a nodules by combining various sectional elastography techniques with age.

Materials and methods: We performed conventional ultrasonography, strain elastography (SE), and shear wave elastography (SWE) on patients. Quantitative parameters recorded included age, cross-sectional and longitudinal area ratios (C-EI/B, L-EI/B), strain rate ratios (C-SR, L-SR), overall average elastic modulus values (C-Emean1, L-Emean1), five-point average elastic modulus values (C-Emean2, L-Emean2), and maximum elastic modulus values (C-Emax, L-Emax).

Results: Histopathological evaluations showed that out of 230 lesions, 45 were malignant, and 185 were benign. The sensitivity and specificity of conventional ultrasonography were 100% and 0%, respectively. In contrast, SE and SWE exhibited higher specificity but lower sensitivity. Crosssectional parameters (C-EI/B, C-SR, C-Emean1, C-Emean2, and C-Emax) outperformed their longitudinal counterparts, with C-SR and C-Emax showing the highest specificity (72.43% and 73.51%) and satisfactory sensitivity (80.00% and 88.89%). Combining age with C-SR and C-Emax significantly improved diagnostic efficiency, achieving a sensitivity of 97.78% and a specificity of 77.30%.

Conclusion: Integrating age with C-SR and C-Emax effectively reduces unnecessary biopsies for most BI-RADS 4a benign lesions while maintaining a very low misdiagnosis rate.
