评估超声高清微血流成像(HD-MFI)技术在鉴别乳腺结节良恶性中的应用价值。
这是一项前瞻性研究。选取2022年3月至2022年6月于中国人民解放军总医院第一医学中心行乳腺常规超声检查提示BI-RADS 3~5类的结节,所有结节均最终获得病理结果。所有结节均分别行彩色多普勒血流成像(CDFI)及HD-MFI扫查,以获得结节的血流情况,并通过HD-MFI获得结节的微血管模式(无血管、线状、树枝状、毛根样及蟹足样)。比较CDFI及HD-MFI对良性结节与恶性结节的血流检出情况及良性结节与恶性结节HD-MFI微血管模式的差异,通过ROC曲线对比分析CDFI与HD-MFI对乳腺结节良恶性的诊断效能。
最终共纳入114例患者的119个乳腺结节,其中71个为良性结节,48个为恶性结节。HD-MFI较CDFI可以更多地检测出乳腺结节的3级血流信号(72.3% vs 20.1%)。在HD-MFI中,良恶性结节均多为2、3级血流信号,但恶性结节的3级血流信号比例显著高于良性结节(85.4% vs 63.4%,P<0.05)。HD-MFI显示良性结节多为无血管、线状或树枝样血管模式,恶性结节多为毛根样或蟹足样模式,微血管模式差异有统计学意义(P<0.05)。HD-MFI对乳腺结节良恶性的诊断特异度(91.5% vs 81.7%)、准确度(86.6% vs 82.4%)、阳性预测值(86.4% vs 75.5%)及曲线下面积[0.854(95%CI:0.777~0.912)vs 0.825(95%CI:0.745~0.889)]均高于CDFI。
与CDFI相比,HD-MFI可以更敏感地检出乳腺结节的血流信号,其描绘的血管模式可以为乳腺结节良恶性的鉴别诊断提供更多的血流信息。

To evaluate the value of ultrasonic high-definition micro-flow imaging (HD-MFI) in differentiating benign and malignant breast masses.
This was a prospective study in which all the patients were enrolled from the First Medical Center, Chinese PLA General Hospital from March 2022 to June 2022, with all masses classified as breast imaging reporting and data system (BI-RADS) 3-5 categories and confirmed by pathology. The blood flow of all masses was evaluated by color Doppler flow imaging (CDFI) and HD-MFI, respectively, and the microvascular patterns (avascular, linear, tree-like, root hair-like, and crab claw-like) of all the masses were assessed by HD-MFI. The detection of blood flow between benign and malignant masses by CDFI and HD-MFI was compared respectively, as well as the differences in microvascular patterns detected by HD-MFI. The diagnostic efficacy of CDFI and HD-MFI in the diagnosis of breast masses was assessed and compared by receiver operating characteristic (ROC) curve analysis.
A total of 114 patients with 119 breast masses were enrolled in this study, and there were 71 benign and 48 malignant masses. More Alder's grade 3 blood flow signals were detected by HD-MFI than by CDFI (72.3% vs 20.1%). On HD-MFI, both benign and malignant breast masses were mostly displayed as Alder's grades 2 and 3, and the proportion of grade 3 malignancies was higher than that of benign masses (85.4% vs 63.4%, P<0.05). Avascular, line-like, and tree-like microvascular patterns were more frequently seen in benign masses by HD-MFI, while root hair-like and crab claw-like patterns were more frequent in malignant masses (P<0.05). The diagnostic specificity (91.5% vs 81.7%), accuracy (86.6% vs 82.4%), positive predictive value (PPV) (86.4% vs 75.5%), and area under the curve [0.854 (0.777~0.912) vs 0.825 (0.745~0.889)] of HD-MFI were higher than those of CDFI.
HD-MFI is a more sensitive technique in detecting blood flow of breast masses in comparison with CDFI. HD-MFI could provide more blood flow information in differentiating benign and malignant breast masses through microvascular patterns.
