食蟹猴动物实验在PET/CT扫描检查中的注意事项

目的 寻找食蟹猴动物实验在PET/CT扫描检查中最佳的扫描参数,获得最佳图像.方法 两只食蟹猴为一雄一雌,对两只食蟹猴分别采用CT多参数扫描和PET的多时段动态断层扫描.结果 扫描条件采用420 mAs、120 kV时,可以获得最佳的图像分辨率和最轻的伪影.PET扫描多时段动态断层扫描的图像中,40～60 min的图像可以获得最佳图像效果.结论 食蟹猴在PET/CT机上行动物实验前,应进行预扫描,选择最佳的扫描参数,才能获得满意的实验结果.

Guidelines for PET/CT scanography in animal experiment of Macaca fascicularis

Objective To search for the best scanning parameters of PET/CT scanning examination in animal experiment of Macaca fascicularis,and to obtain the best images.Methods One male and one female monkeys respectively received the CT multiparameter scanning and PET multi-time period dynamic tomoscan.Results When the scanning conditions were 420 mAs and 120 kV,the best resolution ratio and the lightest constructed defect could be obtained.In the images of PET multi-time period dynamic tomoscan,the best image effects could be obtained from the images within 40-60 min.Conclusion Before the animal experiment of Macaca fascicularis on the PET/CT machine,the monkeys should receive the pre-scanning.And the best scanning parameters should be selected in order to obtain satisfactory results in the experiment.
