摘　　要：阐述小动物PET及PET-CT技术特点及在分子影像学中的应用。小动物PET及PET-CT采用多项新技术，分辨率明显提高，结合小动物CT实现了图像融合。小动物PET及PET-CT实现了在活体上非侵入性分子水平显像，是研究分子影像的尖端设备。The review article introduce molecular imaging equipment small animal PET and PET- CT＇s philosophy and technique feature, small animal PET and PET-CT apply many new techniques and images resolution has obviously raising, as same time, small animal PET and small animal CT may come true image fusion, small animal PET and PET-CT permit us to engage molecular level imaging in vivo without invading, so small animal PET and PET-CT are good tool in medical molecular imaging.
