High-intensity focused ultrasound (HIFU) thermotherapy is a promising technique for local tumor destruction of solid organs. Temperature is the important parameter which impacts the curative effects of thermotherapy. For safety and efficiency reasons, it is necessary to monitor the temperature changes inside body in real-time, non-invasively and precisely. Recently MRI methods employed for temperature monitoring during HIFU therapy have been paid more and more attentions to. This paper introduces the general principles of non-invasive temperature monitoring using MRI. The authors also review the development of this technique and point out some problems that need to be solved.
高强度聚焦超声（HIFU）热疗是一种用于实体器官局部肿瘤破坏的有前景的技术。温度是影响热疗疗效的重要参数。出于安全和效率的原因，有必要实时、非侵入性且精确地监测体内温度变化。近年来，用于HIFU治疗期间温度监测的MRI方法受到了越来越多的关注。本文介绍了使用MRI进行非侵入性温度监测的一般原理。作者还回顾了该技术的发展，并指出了一些需要解决的问题。
