Ultra-low dose chest computed tomography: Effect of iterative reconstruction levels on image quality.
TLDR
In comparison with the FBP technique, ASIR-V enhanced quantitative image quality parameters at all ultra-low doses tested and showed consistency with body size and collimation, Hence, ASir-V may be useful for improving image quality of chest CT at ultra- low doses. Expand
Can use of adaptive statistical iterative reconstruction reduce radiation dose in unenhanced head CT? An analysis of qualitative and quantitative image quality
TLDR
There was no significant difference in qualitative image quality between full dose FBP and dose reduced ASIR, and CNR improved in DR ASIR compared to FD FBP mostly due to increased contrast, not reduced noise. Expand
Image quality with iterative reconstruction techniques in CT of the lungs—A phantom study
TLDR
All iterative techniques improved CNR in chest CT and IMR1 Sharp+ proved advantageous with respect to image quality in CT of the lungs. Expand
CT image quality over time: comparison of image quality for six different CT scanners over a six‐year period
TLDR
The results from this study indicate that there is minor drifting in the image noise and uniformity and in the spatial resolution over time for CT scanners, independent of vendors. Expand
Improved Liver Lesion Conspicuity With Iterative Reconstruction in Computed Tomography Imaging.
TLDR
The results in this study indicate that the possibility for radiation dose reduction using iterative reconstruction techniques depends on both reconstruction technique and the CT scanner model used. Expand
100 days with scans of the same Catphan phantom on the same CT scanner
TLDR
Test results in this study were stable over time for both scan techniques, but further studies on different CT scanners are required to confirm that this also holds true for other systems. Expand
Image Quality Measured From Ultra-Low Dose Chest Computed Tomography Examination Protocols Using 6 Different Iterative Reconstructions From 4 Vendors, a Phantom Study.
TLDR
This study shows the importance of evaluating IR when introduced clinically, and model-based algorithms showed lower NPS peak frequencies at the lowest doses, indicating a coarser and blotchier noise texture. Expand
Choosing the Best Reconstruction Technique in Abdominal Computed Tomography: A Systematic Approach
TLDR
This study indicates that the preferred choice for reconstruction of CT liver examinations performed with the Toshiba Aquilion ONE should be the FC18 filter with IR, although the IR technique did not significantly improve lesion detectability and did not compensate for the dose reduction in this study. Expand
Quantitative Measurements Versus Receiver Operating Characteristics and Visual Grading Regression in CT Images Reconstructed with Iterative Reconstruction: A Phantom Study.
TLDR
Improved quantitative measurements in images reconstructed with iterative reconstruction compared to FBP are not equivalent to improved diagnostic image accuracy. Expand
Image texture and radiation dose properties in CT
TLDR
The results indicate that GE potentially has less image noise than Toshiba for larger patients. Expand
