目的比较冠状动脉CT血管成像(cCTA)新迭代图像重建技术与传统滤过反投影技术(FBP)在影像噪声、影像质量和诊断准确性方面的差异及降低辐射剂量的可能性。方法连续65例病人[男48例,平均年龄(59.3±7.7)岁]进行前瞻性cCTA和冠状动脉导管造影(CCA)。采用所有投影的全辐射
Objective To compare the differences between the new iterative image reconstruction technique of coronary CT angiography (cCTA) and traditional filtered back projection (FBP) in terms of image noise, image quality and diagnostic accuracy, and to reduce the possibility of radiation dose. Methods A total of 65 consecutive patients (48 males, mean age 59.3 ± 7.7 years) underwent prospective cCTA and coronary artery catheterization (CCA). Use all projected full radiation
