【摘要】 探讨彩色超声剪切波弹性成像(shear wave elastography, SWE)及超微血管显像(superb microvascular imaging, SMI)在乳腺良性与恶性肿瘤诊断中的应用。根据术后病理结果或穿刺活检结果,将128例乳腺肿块疾病患者分为良性组和恶性组,分别实施SWE、SMI检测。结果发现,两组正常组织弹性模量最大值Emax2差异无统计学意义(P>0.05);恶性组肿块弹性模量最大值Emax1、Eratio(Emax1/Emax2)值显著高于良性组(P<0.05)。联合检测敏感度、准确度、ROC曲线下面积均显著高于单项检测(P<0.05)。证实SWE联合SMI能显著提高乳腺肿瘤诊断的敏感度、准确度,具有极高的诊断价值。更多还原

【Abstract】 The application of shear wave elastography(SWE) and superb microvascular imaging(SMI) on diagnosis of benign breast lesions and malignant tumor was studied. 128 breast masses patients were chosen and assigned to benign group and malignant group according to pathological examination or aspiration biopsy results. SWE and SMI were performed. Results showed that elasticity maximum of normal tissue(Emax2) between groups showed no significant difference(P>0.05); Elasticity maximum of malignant masses(Emax1) and Eratio(Emax1/Emax2) values in malignant group were significantly higher than those of benign group(P<0.05). Diagnosis sensitivity, accuracy and area under the curve based on combined examination was significantly higher than that of single examination(P<0.05). It was found that SWE combined with SMI could increase the diagnosis sensitivity and accuracy of breast tumor.更多还原
