A Liver Phantom Study: CT Radiation Dose Reduction and Different Image Reconstruction Algorithms Affect Diagnostic Quality
TLDR
This study shows that iterative reconstruction algorithms, in particular Veo, improve lesion detectability in a liver phantom, however, a too aggressive dose reduction may result in poorer image quality. Expand
Comparing five different iterative reconstruction algorithms for computed tomography in an ROC study
TLDR
Only two algorithms improved lesion detection, even though noise reduction was shown with all algorithms, while three algorithms did not significantly improve lesion detectability. Expand
Radiation exposure in patients treated with endovascular aneurysm repair: what is the risk of cancer, and can we justify treating younger patients?
TLDR
Treating younger patients with EVAR poses a low ACR of 0.65% (15-year standard surveillance) compared to a lifetime cancer risk of 44%. Expand
Image Quality in Oncologic Chest Computerized Tomography With Iterative Reconstruction: A Phantom Study
TLDR
Quantitative image quality parameters in oncologic chest CT are improved with MBIR compared with FBP and simpler iterative reconstruction algorithms. Expand
Changes in Dose-Area Product, Entrance Surface Dose, and Lens Dose to the Radiologist in a Vascular Interventional Laboratory when an Old X-ray System Is Exchanged with a New System
TLDR
DAP and ESD from the X-ray system were reduced for all procedures, and the reduction was greater in the more radiation-demanding procedures. 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
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
[Radiation-induced cataracts].
TLDR
The dose limit for the lens of the eye for occupationally exposed workers is based on outdated threshold doses for radiation-induced cataracts, but recent studies have shown that injuries may occur at significantly lower radiation doses than previously assumed. Expand
Benchmarking Of a New Automatic Ct Radiation Dose Calculator.
TLDR
Estimated effective doses derived from a new image-based software tool was benchmarked against the corresponding doses from a dose calculator and a conversion coefficient method and resulted in lower dose than CT-Expo for all the organs. Expand
