PET/MRI多模态成像预测肿瘤放化疗疗效研究进展

Progresses of PET/MRI in predicting tumor response to chemoradiotherapy

近年来,PET/MRI作为一种新兴的多模态成像技术正逐步应用于临床检查。不同患者或疾病对放化疗的敏感性存在差异,在治疗前及治疗初期快速、准确、无创、有效地预测肿瘤对放化疗的敏感性对制定个体化治疗方案具有重要意义。PET/MRI可同时提供肿瘤的生物学和微环境信息,在预测疗效方面具有巨大的潜力。本文对PET/MRI多模态成像预测肿瘤放化疗疗效的研究进展进行综述。

Recently,as a newly developed multi-modality imaging technology,PET/MRI is gradually applied to clinical examination.The sensitivity of chemoradiotherapy shows great differences between different patients and different diseases.It is important to predict tumor sensitivity to chemoradiotherapy easily,accurately,noninvasively and effectively before and after treatment for individual therapy.PET/MRI can provide information about tumor biology and microenvironment,and has a huge potential to predict tumor response to chemoradiotherapy.The research progresses of PET/MRI in predicting tumor response to chemoradiotherapy were reviewed in this article.
