摘　　要：磁共振声辐射力成像(MR-ARFI)将声辐射力与MRI技术相结合,作为一种新兴的高强度聚焦超声(HIFU)治疗监控技术,能够通过探测组织内的微小位移而间接反映组织弹性,具有安全、简便、无需其他激励装置等优点。本文对MR-ARFI的原理、相关序列及其在生物医学方面的应用进展进行综述。Magnetic resonance acoustic radiation force imaging(MR-ARFI),which combines pulsed acoustic radiation with MRI,is a monitoring technology for high-intensity focused ultrasound(HIFU)treatment.With the advantages of safety,simplicity and independent of excitation devices,MR-ARFI can detect elasticity of tissue through tiny displacements within local tissue.The principles,frequently used sequences of MR-ARFI and their applications in biomedical applications were reviewed in this article.
