摘要/Abstract

摘要： 本次研究的目的是分析在乳腺非肿块样强化病变的（NMLE）良/恶性鉴别方面，超声造影（CEUS）及动态增强磁共振成像（DCE-MRI）的诊断效能。实验选取了NMLE病变患者120例，分别给予CEUS及DCE-MRI检测，并与病理结果进行了比较。实验结果显示，经病理确诊恶性病变92例、良性病变28例；CEUS表现中，恶性病变的高增强、快进增强和快出消退比例明显高于良性病变（P<0.05）；DCE-MRI表现中，恶性病变呈节段分布、内部强化呈簇状比例明显高于良性病变（P<0.05），而表观弥散系数（ADC）值明显低于良性病变（P<0.05）。两种方法对NMLE的诊断效果无显著性差异。本次研究证实，CEUS及DCE-MRI在NMLE良/恶性病变鉴别工作中均具有较高效能。

Abstract: The purpose of this study was to investigate the value of contrast-enhanced ultrasound (CEUS) and dynamic enhanced magnetic resonance imaging (DCE-MRI) in the diagnosis of benign and malignant breast lesions of non-mass-like enhancement (NMLE). There were 120 patients with NMLE lesions who were selected and be examined by CEUS and DCE-MRI respectively. The experimental results showed that 92 cases of malignant lesions and 28 cases of benign lesions were confirmed by pathology. In CEUS, the proportion of high enhancement, fast-forward enhancement and fast-out regression in malignant lesions were significantly higher than that in benign lesions (P<0.05). In DCE-MRI, the proportion of malignant lesions with segmental distribution and internal enhancement in clusters were significantly higher than that of benign lesions (P<0.05), while the apparent diffusion coefficient (ADC) was significantly lower than that of benign lesions (P<0.05). There was no significant difference between these two methods in the diagnostic efficacy for breast NMLE lesion. This study confirmed that CEUS and DCE-MRI have good application value in the diagnosis of benign and malignant lesions of NMLE.
