RATIONALE AND OBJECTIVES This study aimed to evaluate the correlation of quantitative measurements with visual grading regression (VGR) and receiver operating characteristics (ROC) analysis in computed tomography (CT) images reconstructed with iterative reconstruction. MATERIALS AND METHODS CT scans on a liver phantom were performed on CT scanners from GE, Philips, and Toshiba at three dose levels. Images were reconstructed with filtered back projection (FBP) and hybrid iterative techniques… Expand
Image quality and radiation dose reduction in chest CT in pulmonary infection
Dose reduction achieved in the follow-up CT scans, although a lower IQ still allows a good diagnostic confidence, as measured by the VGC analysis. Expand
Comparison of full-iodine conventional CT and half-iodine virtual monochromatic imaging: advantages and disadvantages
Reducing the dose of iodine contrast medium is essential for chronic kidney disease patients to prevent contrast-induced nephropathy and should be aware about the advantages and disadvantages associated with virtual monochromatic imaging with reduced iodine dose. Expand


Six iterative reconstruction algorithms in brain CT: a phantom study on image quality at different radiation dose levels.
The four statistical IR algorithms evaluated in the study all improved the general image quality compared with FBP, with improvement seen for most or all evaluated quality criteria. Expand
Iterative reconstruction algorithm for CT: can radiation dose be decreased while low-contrast detectability is preserved?
As the radiation dose at CT decreases, the IR algorithm does not preserve the low-contrast detectability and image quality of computed tomography at different radiation dose levels reconstructed with iterative reconstruction (IR) and filtered back projection (FBP). Expand
Objective performance assessment of five computed tomography iterative reconstruction algorithms.
This study provides performance assessment of the iterative algorithms available from several mainstream CT manufacturers and shows that VEO™ required long reconstruction times, while all other algorithms produced reconstructions in real time. Expand
The Detection of Focal Liver Lesions Using Abdominal CT: A Comparison of Image Quality Between Adaptive Statistical Iterative Reconstruction V and Adaptive Statistical Iterative Reconstruction.
Investigation of image quality characteristics of abdominal computed tomography (CT) scans reconstructed with adaptive statistical iterative reconstruction V (ASIR-V) vs currently using applied adaptive statisticalIterative reconstruction (ASir) found images analyzed using 50% ASIR-v were significantly better than three different series of ASIR or other ASir-V conditions at providing diagnostically acceptable CT scans without compromising image quality and in the detection of focal liver lesions.

Correlation of the clinical and physical image quality in chest radiography for average adults with a computed radiography imaging system.
The results support the value of using CNR and eDE in the evaluation of quality in clinical thorax radiography and medical physics experts may use the physical image quality metrics described here in quality assurance programmes and optimisation studies with a degree of confidence that they reflect the clinical image quality in chest CR images acquired without an antiscatter grid.

Degradation of CT Low-Contrast Spatial Resolution Due to the Use of Iterative Reconstruction and Reduced Dose Levels.
For radiation dose reductions of 25% or more, the ability to resolve the four 6-mm rods in the ACR CT accreditation phantom can be lost. Expand
Correlation of clinical and physical-technical image quality in chest CT: a human cadaver study applied on iterative reconstruction
The results demonstrate that noise assessments in a uniform phantom overestimate the potential dose reduction for the SAFIRE IR algorithm, and an optimised contrast-detail phantom could improve the use of Contrast-detail analysis for image quality assessment in chest CT imaging. Expand
An anthropomorphic phantom for receiver operating characteristic studies in CT imaging of liver lesions.
The phantom and the ROC methodology may, with a set of suggested improvements, be used for comparison of the performance in different CT laboratories, and to establish the dose needed to ensure adequate image quality for a particular scanner. Expand
A method for characterizing and matching CT image quality across CT scanners from different manufacturers
Matching image appearance in terms of resolution, noise magnitude, and noise texture provides a quantitative and reproducible strategy to improve consistency in image quality among different CT scanners and reconstructions. Expand
Paediatric cardiac CT examinations: impact of the iterative reconstruction method ASIR on image quality – preliminary findings
Reconstruction including 20% to 40% ASIR slightly improved the conspicuity of various paediatric cardiac structures in newborns and children with respect to conventional reconstruction (filtered back-projection) alone. Expand
