Several studies have investigated the role of advanced magnetic resonance imaging (MRI) techniques, such as diffusion-weighted imaging (DWI), to improve the specificity of MRI for the evaluation of breast lesions. Potential roles for DWI and the apparent diffusion coefficient in characterizing breast tumors and distinguishing malignant from benign tissues have been reported. This article discusses the clinical applications of breast DWI, including literature results, technical issues and limitations, and the potential applications. The analysis of DWI at our institution is also discussed. The establishment of standard DWI protocols and diagnostic criteria is necessary to ensure accuracy and reproducibility at different centers.
多项研究探讨了先进的磁共振成像(MRI)技术,如扩散加权成像(DWI),在提高MRI评估乳腺病变特异性方面的作用。已有报道称DWI及表观扩散系数在乳腺肿瘤特征化以及区分恶性与良性组织方面的潜在作用。本文讨论了乳腺DWI的临床应用,包括文献结果、技术问题与局限性以及潜在应用。还讨论了我们机构对DWI的分析。建立标准的DWI方案和诊断标准对于确保不同中心的准确性和可重复性是必要的。
