中文摘要：

糖尿病已成为危害人类健康的常见病和多发病。胰岛细胞移植为糖尿病治疗带来新的希望。近年来，分子影像学技术包括光学显像、核素显像、MRI及超声成像等，可在活体条件下无创地进行移植的胰岛细胞显像，为胰岛细胞移植监测提供了灵敏及特异的监测方法。特别是近年来胰高血糖素样肽1类似物胰岛细胞显像的成功，为胰岛细胞移植监测提供了崭新的方法，显示了良好的应用前景。

英文摘要：

Diabetes is significant public health problem. Islet transplantation has been a promising treatment for diabetes. Recently, molecular imaging methods like optical imaging, radionuclide imaging, MRI and US, could monitor islet transplantation in vivo via non-invasive way and provide high sensitive and specific monitoring methods for islet transplantation. Especially in recent years, the success of islet cell imaging with the glucagon like peptide 1 analogue, brings a new method for the monitoring of islet cell transplantation and demonstrates favorable prospect in clinical practice.
