AI noise reduction and the timing of its application during post-processing had a significant impact on the contrast and noise of DECT maps. The DECT maps with AI noise reduction applied to X-ray tube A and B data showed the lowest noise levels. In addition to noise reduction, the contrast levels were slightly changed. An example of the three post-processing versions of the same image is shown in Figure 4.
