Abstract
Diffusion-weighted magnetic resonance (MR) imaging (DWI) has shown promise for improving the positive predictive value of breast MR imaging for detection of breast cancer, evaluating tumor response to neoadjuvant chemotherapy, and as a noncontrast alternative to MR imaging in screening for breast cancer. However, data quality varies widely. Before implementing DWI into clinical practice, one must understand the pertinent technical considerations and current evidence regarding clinical applications of breast DWI. This article provides an overview of basic principles of DWI, optimization of breast DWI protocols, imaging features of benign and malignant breast lesions, promising clinical applications, and potential future directions.
摘要
扩散加权磁共振成像（DWI）已显示出在提高乳腺磁共振成像检测乳腺癌的阳性预测值、评估肿瘤对新辅助化疗的反应以及作为乳腺癌筛查中磁共振成像的非对比替代方法方面的前景。然而，数据质量差异很大。在将DWI应用于临床实践之前，必须了解乳腺DWI临床应用的相关技术考量和当前证据。本文概述了DWI的基本原理、乳腺DWI方案的优化、乳腺良恶性病变的影像学特征、有前景的临床应用以及潜在的未来发展方向。
