The recent advance in hybrid imaging techniques enables offering simultaneous positron emission tomography (PET)/magnetic resonance imaging (MRI) in various clinical fields. F-fluorodeoxyglucose (FDG) PET has been widely used for diagnosis and evaluation of oncologic patients. The growing evidence from research and clinical experiences demonstrated that PET/MRI with FDG can provide comparable or superior diagnostic performance more than conventional radiological imaging such as computed tomography (CT), MRI or PET/CT in various cancers. Combined analysis using structural information and functional/molecular information of tumors can draw additional diagnostic information based on PET/MRI. Further studies including determination of the diagnostic efficacy, optimizing the examination protocol, and analysis of the hybrid imaging results is necessary for extending the FDG PET/MRI application in clinical oncology.
混合成像技术的最新进展使得在各个临床领域能够同时进行正电子发射断层扫描(PET)/磁共振成像(MRI)。F-氟脱氧葡萄糖(FDG)PET已广泛用于肿瘤患者的诊断和评估。来自研究和临床经验的越来越多的证据表明,FDG PET/MRI在各种癌症中能够提供比传统放射成像(如计算机断层扫描(CT)、MRI或PET/CT)相当或更优的诊断性能。利用肿瘤的结构信息和功能/分子信息进行联合分析可以基于PET/MRI获取更多诊断信息。为了扩大FDG PET/MRI在临床肿瘤学中的应用,有必要进行进一步的研究,包括确定诊断效能、优化检查方案以及分析混合成像结果。
