采用声触诊组织量化技术定量分析正常乳腺实质

目的探讨声脉冲辐射力(ARFI)声触诊组织量化(VTQ)技术定量分析正常乳腺实质的价值。方法检测100名正常女性双侧乳腺实质的VTQ值,并结合钼靶X线结果、不同年龄段及生理阶段进行分析。结果本组无脂肪型乳腺。双侧乳腺实质厚度在不同钼靶X线结构分型间差异无统计学意义(P均>0.05)。随着钼靶X线腺体结构致密度的增加,双侧乳腺实质VTQ值增加,不均匀致密型乳腺VTQ值高于散在分布型乳腺(P<0.01);多量致密型乳腺VTQ值高于不均匀致密型乳腺(P<0.05)。双侧乳腺实质厚度及VTQ值在不同年龄组间的差异无统计学意义(P均>0.05)。双侧乳腺实质厚度和VTQ值在性成熟期大于老年期(P均<0.05)。结论利用VTQ值可定量分析乳腺的密度。

Virtual touch tissue quantification technology in assessment of normal mammary gland parenchyma

Objective To investigate the feasibility of virtual touch tissue quantification (VTQ) of acoustic radiation force impulse in assessing the normal mammary gland parenchyma. Methods VTQ value of 100 normal subjects was measured in the normal mammary gland parenchyma and analyzed combining with mammographic density, age and menstrual stage. Results There was no fatty mammary in this group. The breast glandular thickness had no statistical differences among all the mammographic density genotyping (P>0.05). However, VTQ value increased with the increasing of mammographic density. VTQ value of heterogeneously dense parenchyma was higher than that of scattered parenchyma (P<0.01), while VTQ value of more dense parenchyma was higher than that of heterogeneous dense parenchyma (P<0.05). The breast glandular thickness and VTQ value had no statistical difference between different age groups (P>0.05), but in mature stage were both higher than those in old stage (P<0.05). Conclusion VTQ value of mammary gland parenchyma can be used to indicate breast density quantitatively.
