Image quality comparison of a nonlinear image-based noise reduction technique with a hybrid-type iterative reconstruction for pediatric computed tomography

Compared to adults, pediatric patients are more sensitive to ionizing radiation and have greater risk of developing cancer [1]. To mitigate this issue, various techniques, such as automated tube current modulation and the bismuth breast shield, have been developed for dose reduction in pediatric computed tomography (CT) examinations [2,3]. In addition, vendors have recently developed iterative reconstruction (IR) techniques to suppress increased noise in low-dose CT images and can potentially reduce the radiation dose without compromising image quality [4 –6].
