Comparison of objective image noise measurements. Images at the level of the descending aorta on the standard-dose CT with FBP and low-dose CT with FBP, ASIR, and MBIR. Low-dose MBIR CT demonstrated significantly reduced image noise in comparison with standard-dose FBP CT (p < 0.001) with a mean noise reduction of 29.3 ± 8.2%.
