| 中文摘要: |
| 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。 |
| 英文摘要: |
| 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. |
