Automatic sensory change processing in adults with attention deficit and hyperactivity disorder: a visual mismatch negativity study
In addition to higher-order executive functions, underlying sensory processing ability is also thought to play an important role in...

Automated tube voltage adaptation in head and neck computed tomography between 120 and 100 kV: effects on image quality and radiation dose
IntroductionLow tube voltage allows for computed tomography (CT) imaging with increased iodine contrast at reduced radiation dose. We sought to...

CT of the pancreas: comparison of image quality and pancreatic duct depiction among model-based iterative, adaptive statistical iterative, and filtered back projection reconstruction techniques
The purpose of this study is to compare CT images of the pancreas reconstructed with model-based iterative reconstruction (MBIR), adaptive...

Iterative Reconstruction Techniques: What do they Mean for Cardiac CT?
Cardiac computed tomography (CT) is a highly demanding and relatively new CT application that has evolved during the last two decades and for the...

Artifact reduction strategies for prosthetic heart valve CT imaging
Multislice CT evaluation of prosthetic heart valves (PHV) is limited by PHV-related artifacts. We assessed the influence of different kV settings, a...

Step and shoot coronary CT angiography using 256-slice CT: effect of heart rate and heart rate variability on image quality
ObjectiveTo evaluate the effect of heart rate variability (HRV) and heart rate (HR) on intra-image “motion” and inter-image “stairstep” artefacts in...

Gated Multidetector Computed Tomography
Background and Purpose:Streak artifacts caused by aneurysm clips and coils impede image quality in multidetector computed tomography (MDCT). The...

Prospective ECG-gated 320 row detector computed tomography: implications for CT angiography and perfusion imaging
Cardiac multidetector computed tomography has evolved from early four detector systems that first demonstrated the feasibility of non-invasive...

Impact of the z-flying focal spot on resolution and artifact behavior for a 64-slice spiral CT scanner
The effect of the z -flying focal spot ( z FFS) technology was evaluated by simulations and measurements with respect to resolution and artifact...
