Previous studies have shown crowding alleviation when target and flankers similarity is reduced. However, in the case of contrast dissimilarity, the findings were inconsistent. This study examined the effect of stimulus contrast, particularly contrast dissimilarity, on both overall performance under crowded conditions and the critical distance-the spatial extent of crowding. To this end, we mea...
current screening programme, indicate that such a cardiovascular screening programme appeals to and attracts a large audience. Persons attracted to such a programme seem to constitute a relatively healthy sample of the population, and this needs to be taken into account in the consideration of these results. However, the risk of developing future atherosclerotic disease in screened elderly men ...
Diffusible iodine-based contrast-enhanced computed tomography presents a comparatively new tool kit for imaging fine-scale three-dimensional phenotypes that is rapidly becoming standard anatomical practice. However, relatively few studies have attempted to look at subtle differences in staining protocols or attempted to model tissue reactions to gain insight into staining mechanisms. Here, two ...
Iodixanol (Visipaque, Nycomed, Oslo, Norway) is an iodinated contrast medium in the form of a non-ionic dimer which is iso-osmolar with plasma at all iodine concentrations. There is little evidence regarding its renal tolerance in renal impairment. We therefore undertook a prospective randomized comparison of iodixanol and the non-ionic monomer iohexol (Omnipaque, Nycomed, Oslo, Norway). The se...
The International Mouse Phenotyping Consortium has been established to conduct large-scale phenotyping of the approximately 23,000 single-gene knockout mice generated by the International Knockout Mouse Consortium to investigate the role of each gene in the mouse genome. Of the generated mouse lines, 30% are predicted to be embryonic lethal, requiring the implementation of imaging techniques an...
INTRODUCTION Application of computed tomography for monitoring intracranial stents is limited because of stent-related artifacts. Our purpose was to evaluate the effect of gemstone spectral imaging on the intracranial stent and stent lumen. MATERIALS AND METHODS In vitro, we scanned Enterprise stent phantom and a stent-cheese complex using the gemstone spectral imaging protocol. Follow-up gem...
