较之传统的体外组织培养和活体动物研究,分子影像学可以无创、定量、可重复地对活体内细胞和亚细胞水平的生物学过程做靶向成像,有助于了解疾病的分子通路、信号转导和受体变化等异常,从而阐明疾病的机制以及对治疗的反应。对普遍受关注的有重要临床意义的主要心血管疾病的理解 Compared to traditional in vitro tissue culture and living animal studies, molecular imaging can target noninvasively, quantitatively, and reproducibly the biological processes at the cellular and subcellular levels in vivo, helping to understand molecular pathways of disease, signaling Transduction and receptor abnormalities, so as to clarify the mechanism of the disease and the response to treatment.
