磁共振成像（MRI）作为乳腺X线摄影的辅助技术在乳腺癌的检测、诊断、分期和治疗管理中的适当作用一直是当前许多研究的主题。临床应用决定了成像技术的选择。由于对比度增强的快速动力学导致的时间限制要求在空间和时间分辨率之间进行权衡，从而对灵敏度和特异性产生影响。本文讨论了乳腺MRI技术的一些一般要求和建议，包括专用射频线圈、脉冲序列规范和图像质量考虑因素、脂肪抑制技术、造影剂给药方法以及图像后处理和解释。
The appropriate role for magnetic resonance imaging (MRI) as an adjunct technique to mammography in the detection, diagnosis, staging, and therapy management of breast cancer has been the subject of much current research. The clinical application determines the choice of imaging technique. Time restraints due to the rapid kinetics of contrast enhancement require that trade-offs be made between spatial and temporal resolution, with a resulting effect on sensitivity and specificity. This article discusses some general requirements and recommendations for breast MRI techniques, including dedicated radiofrequency coils, pulse sequence specifications and image quality considerations, fat-suppression techniques, methods of contrast administration, and image postprocessing and interpretation.
