【摘要】：高強(qiáng)度聚焦超聲(HIFU)作為一種熱消融療法,在治療過程中需有良好的監(jiān)控和實時精確的測溫技術(shù)以保證治療的安全性和有效性。MR溫度成像通過具有溫度敏感的參數(shù)進(jìn)行測溫,如弛豫時間、質(zhì)子共振頻率(PRF)、擴(kuò)散系數(shù)、磁化矢量轉(zhuǎn)移等,無創(chuàng)且無輻射,并可實時三維成像。其中,由于質(zhì)子共振頻率(PRF)對溫度具有良好的線性度,且與組織類型不相關(guān)�；赑RF的MR溫度成像成為中高場強(qiáng)(≥1T)系統(tǒng)應(yīng)用的首選,在低場強(qiáng)系統(tǒng)中也有應(yīng)用。本文對PRF MR溫度成像的基本原理及其在監(jiān)控HIFU治療方面的研究進(jìn)展進(jìn)行綜述。
[Abstract]:High intensity focused ultrasound (HIFU) as a thermal ablation therapy, good monitoring and real-time and accurate temperature measurement techniques are needed in the course of treatment to ensure the safety and effectiveness of the treatment. For example, relaxation time, proton resonance frequency (PRF), diffusion coefficient, magnetic vector transfer, etc., are noninvasive and non-radiative, and can be used for 3D imaging in real time. The proton resonance frequency (PRF) has a good linearity to temperature and is not related to the type of tissue. Mr temperature imaging based on PRF has become the first choice in the application of medium and high field intensity (鈮，
