纳米分子影像学

Nanomolecular imaging

纳米科学与分子影像学的结合可形成纳米分子影像学 (Nanomolecularimaging)。纳米分子影像学从广义上是指在纳米转运体 (纳米粒转运载体 )介导下 ,应用分子影像学技术对活体生物化学过程进行细胞和分子水平上的定性和定量研究的一门科学 ,主要包括磁共振纳米分子影像学、光学纳米分子影像学、核医学纳米分子影像学和超声纳米分子影像学。本文主要阐述纳米分子影像学的理论基础、技术方法及潜在的应用价值。

The integration of nanotechnology and molecular imaging will lead to the establishment of a new multidisciplinary subfield, which named as ”Nanomolecular imaging”. Nanomolecular imaging is broadly defined as the characterization and measurement of biologic processes in living animals, model systems, and humans under the nanocarriers mediated transportation at the cellular and molecular level by using remote imaging detectors. Nanomolecular imaging mainly includes four different non invasive, in vivo imaging technologies: radionuclide imaging, magnetic resonance imaging and spectroscopy, optical imaging, and ultrasonic imaging. Positron emission tomography (PET) imaging is an important field of molecular imaging. This article discusses the fundamental theory, critical technologies, and potential application of Nanomolecular imaging.
