Abstract

Breast cancer is the most commonly diagnosed cancer among women worldwide, and early detection remains a principal factor for improved patient outcomes and reduced mortality. Clinically, magnetic resonance imaging (MRI) techniques are routinely used in determining benign and malignant tumor phenotypes and for monitoring treatment outcomes. Static MRI techniques enable superior structural contrast between adipose and fibroglandular tissues, while dynamic MRI techniques can elucidate functional characteristics of malignant tumors. The preferred clinical procedure-dynamic contrast-enhanced MRI-illuminates the hypervascularity of breast tumors through a gadolinium-based contrast agent; however, accumulation of the potentially toxic contrast agent remains a major limitation of the technique, propelling MRI research toward finding an alternative, noninvasive method. Three such techniques are magnetic resonance spectroscopy, chemical exchange saturation transfer, and non-contrast diffusion weighted imaging. These methods shed light on underlying chemical composition, provide snapshots of tissue metabolism, and more pronouncedly characterize microstructural heterogeneity. This review article outlines the present state of clinical MRI for breast cancer and examines several research techniques that demonstrate capacity for clinical translation. Ultimately, multi-parametric MRI-incorporating one or more of these emerging methods-presently holds the best potential to afford improved specificity and deliver excellent accuracy to clinics for the prediction, detection, and monitoring of breast cancer.

摘要

乳腺癌是全球女性中最常被诊断出的癌症,早期检测仍然是改善患者预后和降低死亡率的主要因素。临床上,磁共振成像(MRI)技术常用于确定肿瘤的良恶性表型以及监测治疗效果。静态MRI技术能够在脂肪组织和纤维腺组织之间提供出色的结构对比度,而动态MRI技术则可以阐明恶性肿瘤的功能特征。临床首选的方法——动态对比增强MRI——通过基于钆的造影剂来显示乳腺肿瘤的高血管性;然而,这种具有潜在毒性的造影剂的蓄积仍然是该技术的主要局限性,促使MRI研究朝着寻找一种替代性的非侵入性方法发展。三种这样的技术是磁共振波谱、化学交换饱和转移和非对比扩散加权成像。这些方法能够揭示潜在的化学成分,提供组织代谢的快照,并更显著地表征微观结构的异质性。这篇综述文章概述了乳腺癌临床MRI的现状,并探讨了几种具有临床转化潜力的研究技术。最终,结合一种或多种这些新兴方法的多参数MRI目前最有潜力提高特异性,并为乳腺癌的预测、检测和监测提供卓越的临床准确性。
