OBJECTIVE. The purpose of this study is to assess the image quality and radiation dose
reduction of ultra-low-dose CT using sinogram-affirmed iterative reconstruction (SAFIRE) …

Iterative reconstruction (IR) has the ability to reduce image noise in CT without
compromising diagnostic quality, which permits a significant reduction in effective radiation …

Non-linear iterative reconstruction (IR) algorithms have been increasingly incorporated into
clinical cardiac CT protocols at institutions around the world. Multiple IR algorithms are …

Objectives: This study sought to determine whether a 50%-reduced radiation dose protocol
using iterative reconstruction (IR) preserves image quality and diagnostic accuracy at …

Introduction An ideal organ‐specific insert phantom should be able to simulate the
anatomical features with appropriate appearances in the resultant computed tomography …

Objectives We evaluated the influence of sinogram-affirmed iterative reconstruction
(SAFIRE) on the coronary artery calcium (CAC) score by computed tomography (CT) …

The present study aimed to investigate whether the in-plane resolution property of iterative
reconstruction (IR) of computed tomography (CT) data is object shape-dependent by testing …

OBJECTIVE. The purpose of this study was to determine whether ultralow-radiation-dose
chest CT can be used for quantification of lung density and for emphysema detection in …
