Role of power Doppler techniques and ultrasound contrast enhancement in the differential diagnosis of focal breast lesions

The purpose of this article is to demonstrate the diagnostic impact of ultrasound in differentiating focal breast lesions with special regard on power Doppler and US contrast agents. The sonographic evaluation of breast lesions has become a standard procedure during the past 15 years. Especially the improvement of B-mode resolution and the use of high-frequency probes increased the diagnostic value of US. Assuming that the neoangiogenetic vascular architecture of solid breast lesions can be depicted reliably by color Doppler, many authors tried to differentiate between benignity and malignancy using Doppler criteria such as flow and morphologic aspects. Additionally, adjuvant techniques, such as harmonic imaging and new US contrast agents, are meant to be success-promising tools. Whereas the sensitivity and specificity of color Doppler have varied in different studies, prognostic prediction and treatment monitoring seem to be the future areas of application. To evaluate sufficiently flow signals of very small vessels with low flow velocity, the use of contrast-enhancing agents may be necessary. Nevertheless, an indispensable condition for successful Doppler-based assessment of the entity of breast lesions is the standardization of techniques, evaluation, analysis and weighting of the parameters.

三种超声方法鉴别乳腺良恶性肿块的对比分析

目的：探讨三种不同超声方法对乳腺良恶性肿块的诊断价值。方法：对30个乳腺肿块患者行二维超声常规检查和多普勒检查,并进行超声征象评分和多普勒分析,用设定的三种方法进行良恶性判断,并与病理和手术结果相对照。结果：三种方法进行乳腺肿块的良恶性判断,符合率明显不同（46．7％,60％,83．7％）,其中以二维超声征象评分结合彩色多普勒超声的定量分析,符合率最高。结论：综合二维超声征象评分和彩色血流的定量分析,大大提高了乳腺肿块良恶性判断的准确率,减少了诊断中的主观性。

Appearence of breast masses on sonoelastography with special focus on the diagnosis of fibroadenomas

The aim of this study was to show and correlate the imaging features of breast masses, especially fibroadenomas, using sonoelastography. Two hundred thirty-five patients with 302 breast lesions referred for core needle biopsy participated in the study. All lesions appearing as solid masses on conventional US were included. Out of the included lesions (270), 115 (42.6%) corresponded to histologically confirmed fibroadenomas and 155 (57.4%) to lesions with histologically confirmed diagnoses other than fibroadenomas. These were further subdivided into fibrocystic changes, lesions with low malignancy potential, and malignant lesions. Fibroadenomas were also divided according to histological presentation into three subgroups to allow comparative study based on elastographic scores. All lesions were classified using a four-point scoring system based on ultrasound elastography imaging characteristics. Different presentations were observed for elastographic scores according to histological presentation of fibroadenomas, whereby fibroadenomas with benign characteristics tended to have elastographic classification similar to fibrocystic changes, and complex and hypercellular fibroadenomas had classifications similar to harder lesions. Fibroadenomas are generally classified as category 3 in the BI-RADS® lexicon and are the most commonly found lesions in breast biopsies. Sonoelastography can provide additional information to conventional studies and be used as an auxiliary tool in assessing these masses in clinical practice.     

能量多普勒和三维血管重建在乳腺肿瘤诊断中的应用研究

目的:研究乳腺肿块能量多普勒显像和三维血管重建血流灌注及形态特征的变化。方法:171例乳腺肿块,选用能量多普勒和三维血管重建对照,观察血流程度变化、血流形态特征,定量分析彩色血流灌注面积。结果:三维血管重建显示乳腺癌和良性肿块血流信号比能量多普勒有显著增强效果,两者差异有显著性(P<0.05)。乳腺癌灌注面积显著大于良性肿块,两者差异有显著性(P<0.05)。结论:三维血管重建能有效增强乳腺肿块的血流信号,能量多普勒和三维血管重建对照能显著提高乳腺肿瘤鉴别诊断的价值。     

Contrast-enhanced MRI in breast cancer patients eligible for breast-conserving therapy: complementary value for subgroups of patients

The aim of this study was to identify patients prior to breast-conserving therapy (BCT) who have complementary value of contrast-enhanced magnetic resonance imaging (MRI) over conventional imaging in the assessment of tumor extent. All patients were eligible for BCT according to conventional imaging, and underwent preoperative MRI as part of this study. One hundred and sixty-five patients (166 tumors) were included. MRI was defined to have complementary value if conventional imaging underestimated or overestimated tumor extent (by more than 10 mm compared to histology) and MRI assessed the extent accurately. Logistic regression was employed to identify characteristics that are predictive of the complementary value of preoperative MRI. MRI had complementary value in 39 cases (23%). Patients <58 years old with irregular lesion margins at mammography and discrepancy in tumor extent by more than 10 mm between mammography and ultrasonography had a 3.2× higher chance of accurate assessment at MRI (positive predictive value 50%, negative predictive value 84%, p=0.0002). Preoperative MRI in patients eligible for BCT is more accurate than conventional imaging in the assessment of tumor extent in approximately one out of four patients. Subgroups of patients in whom MRI has complementary value may be defined by the differences in clinical and imaging features.
