【摘要】 超快速动态对比增强MRI(ultrafast MRI)是近年来发展的一项新技术，相较于传统乳腺常规DCE-MRI，以高时间分辨率捕捉造影剂的早期快速流入，获取早期的动力学信息，来更好的来鉴别乳腺良恶性病变。本文在ultrafast MRI的成像原理、优劣势、鉴别乳腺良恶性病变方面的进展及其未来发展趋势进行了综述。更多还原

【Abstract】 Ultrafast dynamic contrast enhanced MRI(ultrafast MRI) is a new technology developed in recent years.Compared with conventional breast DCE-MRI,ultrafast MRI captures the early rapid inflow of contrast agent with high temporal resolution and acquires early dynamic information to better identify benign and malignant breast lesions.In this paper,the imaging principle,advantages and disadvantages of ultrafast MRI,the identification of benign and malignant breast lesions and its future development trend are reviewed.更多还原
