Coronary CT angiography: radiation dose reduction

By Dr K A Abdullah, Dr M F McEntee, Dr W Reed & Dr P L Kench

In this article, we present a summary of our work, in which we evaluate the use of CT iterative reconstruction (IR) for radiation dose reduction and the impact on diagnostic image quality particularly in coronary CT angiography (CCTA). We demonstrate that IR is a powerful tool that enables radiation dose reduction without significant impact on diagnostic image quality.
