basis of PET performance tests, PET quantification value calobration on 3D-PET among facility

据说，PET SUV值在用于图像重建的PET设施中是不同的。为了公平地比较PET的性能，有必要在相同的条件下对每个PET设备和机器进行测试。我们能够在缩短的时间过程中对临床状况进行PET性能测试。根据“日本肿瘤学FDG-PET/CT数据采集协议体模实验2指南“进行实验，以获得一些设施之间的SUV值。通常SUV值以最大值和平均值表示。30分钟采集的平均值在测试设施中接近，但其最大值各不相同。这被认为是由于每台机器的分辨率灵敏度不同。为了使用指南2比较PET SUV值，发现需要检查PET体模地球仪的大小和SUV平均值，而最大值可通过图像重建改变。

It is said that PET SUV value is different among PET facilities for image reconstruction. To compare PET performance equitably, it is necessary that each of the PET facilities and machines is tested under the same conditions. We were able to conduct PET performance tests on the clinical condition with reduced time course. The experiment was carried out according to the "Japanese guideline for the oncology FDG-PET/CT data acquisition protocol phantom experiment #2"to get the SUV values among some facilities. Usually the SUV values are expressed in the maximum and the mean. The mean values by 30-minute acquisition were close among the tested facilities, but their maximum values were varied. This is considered to be due to the difference in resolution sensitivity of each machine. To compare PET SUV values using Guideline 2, it was found that the size of PET phantom globe and the SUV mean value are necessary to be examined, while the maximum value was changeable by image reconstruction.
