Abstract
Triple-negative breast cancer(TNBC)is a special subtype of breast cancer with high heterogeneity,high invasiveness,poor efficacy and prognosis.Its estrogen receptor,progesterone receptor and human epidermal growth factor receptor-2 are all negative.Early diagnosis and accurate evaluation is important clinically for the treatment of this tumor.At present,X-ray photography and ultrasonography are more common in clinical screening for breast cancer.But magnetic resonance imaging(MRI)has gradually become a reliable imaging method for the detection and diagnosis of breast diseases due to its high soft tissue resolution,non-invasive and non-radiative advantages.Based on the research literature at home and abroad in recent years,this paper reviews the application of various imaging techniques in the diagnosis of TNBC.The results of literature review show that multimodal MRI can show the unique malignant signs of TNBC patients that are difficult to be detected by X-ray and ultrasound,such as smooth edges,central high signal on T2WI,low ADC value and ring enhancement,so as to improve the diagnostic accuracy.It can provide a reliable imaging basis for the early detection,diagnosis,preoperative evaluation and monitoring of neoadjuvant therapy of TNBC.It is an important imaging technique for the diagnosis of TNBC.关键词
