Abstract

Recognizing the potential of quantitative imaging biomarkers (QIBs) in radiotherapy, many studies have investigated the prognostic value of quantitative MRI (qMRI). With the introduction of MRI-guided radiotherapy systems, the practical challenges of repeated imaging have been substantially reduced. Since patients are treated inside an MRI scanner, acquisition of qMRI can be done during each fraction with limited or no prolongation of the fraction duration. In this review paper, we identify the steps that need been taken to move from MR as an imaging technique to a useful biomarker for MRI-guided radiotherapy (MRgRT).

MR-Linacs 上的定量 MRI：实现生物图像引导的自适应放射治疗

由于认识到定量成像生物标志物（QIBs）在放疗中的潜力，许多研究对定量磁共振成像（qMRI）的预后价值进行了调查。随着磁共振成像引导放疗系统的引入，重复成像的实际挑战已大大降低。由于患者是在核磁共振扫描仪内接受治疗，因此可在每次分次放疗期间采集 qMRI，而分次放疗的持续时间则有限或无需延长。在这篇综述论文中，我们明确了从磁共振成像技术到磁共振成像引导放疗（MRgRT）的有用生物标记物所需采取的步骤。
