摘　　要：磁共振成像(magnetic resonance imaging,MRI)基于其优势已广泛应用于前列腺癌(prostate cancer,PCa)放疗中。具有定量特性的功能MRI(functional MRI,f-MRI)在优化PCa放疗计划设计和位置验证中具有重要临床价值,在提高了放疗效果的同时,f-MRI还为疗效评价提供了可靠参考。本综述对传统和最新f-MRI在PCa放疗中的应用原理和效果进行介绍,以期填补国内空白和完善医学影像理论体系,并为相关从业者提供研究参考。Magnetic resonance imaging(MRI)had been widely used in the process of radiotherapy for prostate cancer(PCa)based on the advantages.Functional MRI(f-MRI)with quantitative characteristic had important clinical value in optimizing the PCa radiotherapy plan design and location verification.While improving the curative effect of radiotherapy,f-MRI also provided a reliable reference for the evaluation of curative effect.This review introduced the application principle and effect of traditional and latest f-MRI in PCa radiotherapy,in order to fill the domestic gap,improve the theoretical system of medical imaging,and provide research reference for relevant practitioners.
