摘要

目的:利用常规乳腺超声检查图像,通过半定量分析建立超声乳腺成分评估分类树:本研究回顾性地纳入了 100 名连续接受乳房 X 线照相术和补充超声波检查的正常女性。根据超声乳腺成分,患者的乳房被分为非致密型和致密型,这与乳腺X光检查的乳腺成分相关。超声波乳房组成是根据纤维腺体组织(FGT)厚度与皮下脂肪和乳腺后脂肪(FAT)厚度的比值进行分类的。此外,还研究了 FGT 中是否存在较高的腺组织成分(GTC),或 FGT 中是否存在明显的脂肪小叶。根据曲线下面积(AUC)计算出非致密乳房和致密乳房之间的分界点:结果:所有 GTC 偏高的病例均为致密型乳房,而所有 FGT 中存在明显脂肪小叶的病例均为非致密型乳房。所有病例、无高 GTC 组、FGT 无明显脂肪小叶组和 FGT 无高 GTC 或明显脂肪小叶组的 FGT 厚度与脂肪比的 AUC 分别为 0.93、0.94、0.99 和 1:结论:GTC 偏高代表乳房致密,FGT 有明显脂肪小叶代表乳房不致密。对于其余病例,FGT 厚度与脂肪厚度比值的临界点为 0.93,超声波两级乳房成分评估的准确率为 100%。

Preliminary study of standardized semiquantitative method for ultrasonographic breast composition assessment.

Preliminary study of standardized semiquantitative method for ultrasonographic breast composition assessment.

Purpose: To develop a classification tree via semiquantitative analysis for ultrasonographic breast composition assessment using routine breast ultrasonography examination images.

Methods: This study retrospectively enrolled 100 consecutive normal women who underwent screening mammography and supplemental ultrasonography. Based on sonographic breast composition, the patients' breasts were classified as nondense or dense, which were correlated with mammographic breast composition. Ultrasonographic breast composition was classified based on the fibroglandular tissue (FGT) thickness-to-subcutaneous fat and retromammary fat (FAT) thickness ratio. In addition, the presence of a high glandular tissue component (GTC) in FGT or the presence of evident fat lobules in FGT was investigated. The cutoff point between the nondense and dense breasts was calculated from the area under the curve (AUC).

Results: All cases with a high GTC were dense breasts, and all cases with evident fat lobules in the FGT were nondense breasts. The AUC of the FGT thickness-to-FAT ratio of all cases, the group without a high GTC, the group without evident fat lobules in the FGT, and the group without a high GTC or evident fat lobules in the FGT were 0.93, 0.94, 0.99, and 1, respectively.

Conclusion: The presence of a high GTC indicated dense breasts, and the presence of evident fat lobules in the FGT represented nondense breasts. For the remaining cases, the cutoff point of the FGT thickness-to-FAT thickness ratio was 0.93 for ultrasonographic two-grade scale breast composition assessment with 100% accuracy.
