Evaluation of Low-contrast Detectability of Different Reconstruction Algorithms and Noise Reduction Intensities in the Upper Abdominal Pseudo-human Phantom

Year: 2025

Type: article

Abstract: PURPOSE: The effects of reconstruction algorithm and noise reduction intensity on low-contrast detectability in abdominal CT examinations were investigated. METHODS: were used as evaluation indices. RESULTS: than the others. Hybrid IR and DLR for body showed equivalent performance regardless of noise reduction intensity, confirming the limitations of low-frequency noise suppression. CONCLUSION: It is important to select a reconstruction algorithm and noise reduction intensity according to the purpose of the examination, and DLR for body sharp is useful for improving image quality and reducing exposure at low doses.
