Magnetic resonance temperature imaging (MRTI) is an enabling technology that has recently demonstrated the potential to bring the emerging minimally invasive image-guided thermal therapy procedures, such as radiofrequency, microwave, laser, ultrasound, and cryosurgery, into the clinical setting with a level of safety and efficacy not previously possible. By coupling the wealth of soft tissue contrast mechanisms available with magnetic resonance imaging with its intrinsic temperature sensitivity, magnetic resonance imaging is in a unique position to provide image-guided treatment planning and verification and quantitative or qualitative feedback during treatment delivery, heightening of the control the physician has over the method, and enhancement of the ability to deliver conformal treatments. The basic principles behind MRTI technology and its application to minimally invasive thermal therapy during ultrasound thermal therapy delivery are reviewed in this study.
磁共振温度成像（MRTI）是一项赋能技术，最近已展现出潜力，能够将诸如射频、微波、激光、超声和冷冻手术等新兴的微创图像引导热疗程序引入临床，实现前所未有的安全性和有效性。通过将磁共振成像丰富的软组织对比机制与其固有的温度敏感性相结合，磁共振成像处于独特地位，可在治疗过程中提供图像引导的治疗计划与验证以及定量或定性反馈，增强医生对该方法的控制能力，并提升实施适形治疗的能力。本研究回顾了MRTI技术背后的基本原理及其在超声热疗过程中对微创热疗的应用。
