心脏肿瘤是一种相对少见的疾病,可分为原发性和转移性心脏肿瘤。其肿瘤细胞的分裂增殖速度快于正常细胞,需要葡萄糖的过度利用才能完成能量代谢、蛋白质合成和细胞增殖。18F-FDG是目前最常用的PET/CT显像剂,18F-FDG PET/CT显像通过评价正常组织与肿瘤组织葡萄糖代谢的差异,对心脏肿瘤进行定位诊断及疗效评价,具有一定的临床应用价值[1],但其定性诊断价值尚不可靠。我们从定位诊断、疗效评价、定性诊断和成像技术优化等4个方面对18F-FDG PET/CT显像在心脏肿瘤中应用的研究进行综述。

Abstract: 18F-FDG PET/CT has been widely used as a powerful tool for the diagnosis and differential diagnosis of cardiac tumors. This article focuses on the research evidence of 18F-FDG PET/CT applied in cardiac tumors from four aspects: positioning diagnosis, qualitative diagnosis, efficacy evaluation and imaging technology optimization, achieving the goal of systematical evaluation of the method. -
