目的fdg PET/CT在炎性心脏病及心脏肿瘤的诊断中具有重要意义。我们试图确定基于体积分析的最佳FDG摄取阈值，并评估FDG PET心肌生理摄取体积与几个临床因素之间的关系。方法对190例患者进行回顾性分析。心脏代谢体积（CMV）定义为在阈值（血池SUVmean x1.5）确定的边界内的体积。结果降主动脉（DA）血池SUVmean (r=0.86，类内相关系数[ICC]=0.93， P
ObjectiveFDG PET/CT plays a significant role in the diagnosis of inflammatory heart diseases and cardiac tumors. We attempted to determine the optimal FDG uptake threshold for volume-based analyses and to evaluate the relationship between the myocardial physiological uptake volume in FDG PET and several clinical factors.MethodsA total of 190 patients were retrospectively analyzed. The cardiac metabolic volume (CMV) was defined as a volume within the boundary determined by a threshold (SUVmean of blood poolx1.5).ResultsThe SUVmean of the blood pool measured in the descending aorta (DA) (r=0.86, intraclass correlation coefficient [ICC]=0.93, P
