| 摘 要： | PET/CT检查中的CT扫描起着重要作用,而在全身PET/CT检查过程受检者接受的放射剂量中,因CT扫描产生的放射剂量占较大比例。本文对PET/CT检查中PET及CT扫描对放射剂量的贡献进行分析,探讨如何在不影响临床对CT图像质量需求的前提下,减少不必要的放射剂量,降低受检者辐射剂量。

| Abstract: | CT scan plays an important role in the test of PET/CT. A large proportion of the radiation dose for examination obtained from whole-body PET/CT is from CT scan. The attribution of the radiation dose of CT scan and PET separately to the total dose from the test of PET/CT was analyzed in this article, in order to explore how to cut down the unnecessary radiation and decrease the radiation dose without impairing CT image qualities determined by the clinic. |
