分子影像学是在分子水平针对活体特征和生物进程的一种成像技术,相对于传统的影像学,它偏向于了解疾病的基础变化、基因分子水平的异常,而不是对由这些分子改变所构成的最终结果进行成像。所以,它最突出的特点,就是用影像手段非创伤性地对活体内参与生理和病理过程的分子进行定性或定量的可视化观察。在分子成像中,制备特异性 Molecular imaging is an imaging technique aimed at living features and biological processes at the molecular level. Compared with traditional imaging, molecular imaging is biased in understanding the basic changes in diseases and the abnormalities in the molecular level of genes rather than in the composition of these molecular changes The final result was imaged. Therefore, its most prominent feature is the use of imaging means to non-invasive qualitative and quantitative visual observation of molecules involved in physiological and pathological processes in vivo. In molecular imaging, specificity is made
