目的：目的：探讨能量多普勒超声（PDUS）在乳腺实性肿块影像学报告和数据系统超声（BI-RADS US）分类中的作用。根据美国放射医师学会（ACR）BI-RADS US词典对病变的US特征进行分类。病变定性评估根据其PDUS属性和定量频谱分析。结果：94个病灶中，良性55个（58.5%），恶性39个（41.5%）。US和PDUS诊断恶性病变的敏感性、特异性、阳性预测值（PPV）和阴性预测值（NPV）分别为100%、58.2%、62.9%、100%和71.8%、81.8%、73.7%、80.4%。良恶性病变的血管数目（p < 0.05）、肿瘤血管的分布、血管形态及电阻率指数> 0.85等指标的差异有统计学意义（p < 0.001）。当超声与PDUS和频谱分析结果相结合时，其敏感性、特异性、PPV和NPV分别为100%、52.7%、60%和100%。对于频谱分析，当RI值为1或更大时，恶性风险显著增加。(C)2007爱思唯尔爱尔兰有限公司保留所有权利。
Objective: To evaluate the contribution of power Doppler ultrasonography (PDUS) to breast imaging reporting and data system ultrasonography (BI-RADS US) categorization of solid breast masses.Materials and methods: Totally 94 solid lesions with histopathological results in 49 patients were included in the study. US features of the lesions were classified according to American College of Radiologists (ACR) BI-RADS US lexicon. Lesions were evaluated qualitatively according to their PDUS properties and quantitatively with spectral analysis. Hypervascularity, penetration of vessels into the mass or branching-disordered course and resistivity index values higher than 0.85 were accepted as probable malignant criteria.Results: Fifty-five of 94 lesions were benign (58.5%), while 39 (41.5%) were malignant histopathologically. The sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of US and PDUS in the diagnosis of malignant lesions were 100%, 58.2%, 62.9%, 100% and 71.8%, 81.8%, 73.7%, 80.4%, respectively. Criteria used for the distinction of malignant and benign lesions like number of vessels (p < 0.05), distribution of tumoral vessels, morphology of vessels and resistivity index values higher than 0.85 showed statistically significant difference (p < 0.001). When sonographic findings were combined with PDUS and spectral analysis findings, sensitivity, specificity, PPV and NPV were 100%, 52.7%, 60% and 100%, respectively.Conclusion: PDUS and spectral analysis have no contribution to BI-RADS US. For the spectral analysis, when RI value is one or greater, malignancy risk significantly increases. (C) 2007 Elsevier Ireland Ltd. All rights reserved.
