摘要
PET/MRI融合了解剖、功能和代谢信息,越来越多地用于临床肿瘤学领域,包括疾病早期诊断、局部分期、全身转移灶的探查以及疗效评价和预后评估等。除了精细的解剖结构外,MRI多参数成像还能提供病变的功能信息,结合PET的代谢信息,能更好地评估肿瘤的良恶性、分级、侵犯范围、鉴别肿瘤复发和放射性坏死。开发新型PET示踪剂、研发优化MRI序列及检查路径,联合高通量图像定量分析方法、影像组学、人工智能等新技术,进一步推进PET/MRI在肿瘤学中的应用。
PET/MRI integrates anatomical,functional and metabolic information,and is increasingly used in the field of clinical oncology,including early diagnosis of disease,local staging,detection of systemic metastases,evaluation of treatment efficacy and prognosis.In addition to fine anatomical structure,MRI multiparametric imaging can also provide functional information of the lesion.Combined with metabolic information of PET,MRI multiparametric imaging can better evaluate the benign and maligant lesions,tumor grade and extent of invasion,and identify tumor recurrence and radiation necrosis.The development of new PET tracers,optimization of MRI sequences and examination paths,combined with high-throughput image quantitative analysis methods,radiomics,artificial intelligence and other new technologies will further promote the application of PET/MRI in oncology.
