细胞代谢紊乱是恶性肿瘤的一个特征,已被用于成像和靶向治疗。在成像方面,18F-FDG PET利用了紊乱的葡萄糖代谢。然而,18F-FDG的代谢成像只探测糖酵解的早期步骤,没有直接捕捉到这一单一途径中这些早期步骤之外的代谢的复杂性。新的成像技术--具有新型放射性示踪剂的PET和基于磁共振的方法--为研究细胞新陈代谢的其他方面和扩大代谢成像设备提供了独特的机会。这篇综述将讨论癌症代谢失调的潜在生物学,重点是葡萄糖、谷氨酰胺和醋酸盐代谢。新的成像策略将在这个生物学框架内讨论,强调每种技术的特定优势和局限性。重点强调了组合模式将在使多参数成像能够充分描述肿瘤生物学特征以更好地指导治疗方面发挥的作用。
Dysregulated cellular metabolism is a characteristic feature of malignancy that has been exploited for both imaging and targeted therapy. With regard to imaging, deranged glucose metabolism has been leveraged using 18F-FDG PET. Metabolic imaging with 18F-FDG, however, probes only the early steps of glycolysis; the complexities of metabolism beyond these early steps in this single pathway are not directly captured. New imaging technologies—both PET with novel radiotracers and MR-based methods—provide unique opportunities to investigate other aspects of cellular metabolism and expand the metabolic imaging armamentarium. This review will discuss the underlying biology of metabolic dysregulation in cancer, focusing on glucose, glutamine, and acetate metabolism. Novel imaging strategies will be discussed within this biologic framework, highlighting particular strengths and limitations of each technique. Emphasis is placed on the role that combining modalities will play in enabling multiparametric imaging to fully characterize tumor biology to better inform treatment.
