乳腺癌是女性常见的恶性肿瘤之一,且其发病呈逐年递增及年轻化趋势,严重危害着女性的健康。与体格检查、乳腺X线摄影及超声检查相比,MRI检查拥有更高的组织分辨率和灵敏度,且无辐射危害,已成为目前诊断乳腺疾病的重要工具。然而,常规动态增强MRI的灵敏度虽高,但特异度相对较低,常造成患者进行了不必要的活检。近年来,随着MRI功能成像序列如扩散加权成像(diffusion weighted Breast cancer is one of the common malignant tumors in women, and its incidence is increasing year by year and younger trend, seriously endangering women’s health. Compared with physical examination, mammography and ultrasound examination, MRI examination has higher tissue resolution and sensitivity, and no radiation hazards, has become an important tool for the diagnosis of breast disease. However, the sensitivity of conventional dynamic contrast-enhanced MRI is high, but its specificity is relatively low, often causing the patient to have unnecessary biopsies. In recent years, with MRI functional imaging sequences such as diffusion weighted imaging (diffusion weighted
