Iterative reconstruction (IR) techniques allow for reductions in computed tomography (CT) radiation doses compared to traditional filtered back projection (FBP) while maintaining image quality. As computer processing power has increased, IR methods have become feasible alternatives to FBP. Studies have found that blending IR with FBP, such as applying 30-50% IR, can reduce patient radiation doses by 20-50% on average compared to full-dose FBP scans, without compromising diagnostic accuracy. IR is particularly beneficial for reducing noise in images of obese patients and for low-dose CT protocols that image outside the primary area of interest. With further advances in computing and IR methods, greater dose reductions may be possible in the future.
