Imaging plays an indispensable role in the diagnosis and treatment of breast cancer. Several new imaging tools are currently being developed for clinical use to improve diagnostic performance and tumor response evaluation. Abbreviated magnetic resonance imaging (MRI) allows shortening scanning time without penalizing diagnostic performances. Ultrafast dynamic contrast-enhanced MRI is a new approach that provides kinetic information and helps identify breast lesions developed in breast with marked background parenchymal enhancement. Intravoxel incoherent motion and kurtosis are parameters of diffusion-weighted imaging (DWI) that bring useful information in breast cancer. High-resolution DWI, allows morphological assessment of lesions without using a contrast agent. High-resolution breast positron emission tomography provides detailed metabolic information on small breast cancer. Photoacoustic imaging utilizes hemoglobin as an intrinsic contrast agent and depicts fine -branching structure of the tumor vessels related to cancer. It is important that experts in breast imaging understand the advantages and limitations of these new techniques in order to offer optimal imaging to each patient.
成像在乳腺癌的诊断和治疗中发挥着不可或缺的作用。目前正在开发几种新的成像工具用于临床，以提高诊断性能和肿瘤反应评估。缩短磁共振成像（MRI）的扫描时间而不影响诊断性能。超快速动态对比增强 MRI 是一种新方法，可提供动力学信息并有助于识别在背景实质增强明显的乳房中发生的乳房病变。体素内不相干运动和峰度是扩散加权成像（DWI）的参数，可为乳腺癌提供有用信息。高分辨率 DWI 允许在不使用造影剂的情况下对病变进行形态评估。高分辨率乳房正电子发射断层扫描提供有关小乳腺癌的详细代谢信息。光声成像是利用血红蛋白作为内在对比剂，并描绘与癌症相关的肿瘤血管的精细分支结构。重要的是，乳腺成像专家了解这些新技术的优势和局限性，以便为每位患者提供最佳的成像。
