不同级别iDose⁴迭代重建技术在冠状动脉CT成像中的应用

Zhongguo shiyan zhenduanxue, 2016
目的评价冠状动脉CT成像（CCTA）中不同级别iDose4迭代重建技术的图像质量、噪声差异,探讨具有最佳图像质量及低噪声的iDose4级别。方法应用Philips,Ingenuity Core 128CT对60例患者行回顾性心电门控CCTA,采集的原始数据分别进行传统滤过反投影法（FBP）和iDose4-1iDose4-7的图像重建。由2名影像诊断学医师采用4分法双盲评价冠状动脉的9个主要分支;记录噪声值、SNR值及CNR值,对数据进行统计学分析,比较8组数据的差异 ...
