OBJECTIVE. The purpose of this article is to review reasonable measures that community
radiologists can realistically implement as a response to the current increased public …

Recent advances in computed tomographic (CT) scanning technique such as automated
tube current modulation (ATCM), optimized x-ray tube voltage, and better use of iterative …

Although there has been increasing recognition of the importance of reducing radiation dose
when performing multidetector CT examinations, the increasing complexity of CT scanner …

Objectives The purpose of this study was to assess the image quality of half-dose (HD) liver
computed tomography (CT) using a model-based iterative reconstruction algorithm (MBIR) …

The risks and benefits of using computed tomography (CT) as opposed to another imaging
modality to accomplish a particular clinical goal should be weighed carefully. To accurately …

Background Coronary artery fractional flow reserve (FFR) derived from CT angiography
(FFTCT) enables functional assessment of coronary stenosis. Prior clinical trials showed …

Objectives To compare routine dose liver CT reconstructed with filtered back projection
(FBP) versus low dose images reconstructed with FBP and adaptive statistical iterative …

OBJECTIVE. The purpose of this study was to evaluate the image quality and diagnostic
performance of low-dose MDCT and CT enterography with adaptive statistical iterative …

Automatic tube current modulation (ATCM) on CT scanners can yield significant reductions
in patient doses. Modulation is based on x-ray beam attenuation in body tissues obtained …

The purpose of this study was to explore the effects of CT slice thickness, reconstruction
algorithm, and radiation dose on quantification of CT features to characterize lung nodules …
