肉芽肿性乳腺炎(granulomatous mastitis,GM)是一种较少见的良性乳腺炎症性疾病,其中多数病灶表现为非肿块样强化,因此与非肿块型乳腺癌(non-mass breast cancer,NMBC)在影像及临床表现中存在较多重叠,所以无创影像学检查鉴别GM与NMBC...肉芽肿性乳腺炎(granulomatous mastitis,GM)是一种较少见的良性乳腺炎症性疾病,其中多数病灶表现为非肿块样强化,因此与非肿块型乳腺癌(non-mass breast cancer,NMBC)在影像及临床表现中存在较多重叠,所以无创影像学检查鉴别GM与NMBC在临床上存在一定困难。多参数MRI通过结合多个MRI序列信息,对病变动态发展过程进行多维度的量化并提供病变特征的关键信息。影像组学通过提取高通量特征,可捕捉肉眼难以识别的信息。本文就近年来多参数MRI及影像组学在鉴别GM与NMBC的研究进行综述,并分析目前研究的局限性、指出未来的研究方向,旨在减少不必要的有创检查,指导早期临床治疗方案的选择及提高患者预后生活质量。展开更多
