278, P = 0.235). Failures could be explained in all cases

by the presence of leaks or holes in the neointima at the level of the transition zones.

FDs did not successfully treat most bifurcation aneurysms, at least in this animal model.”
“Degree of pupil dilation has been shown to be a valid and reliable measure of cognitive Raf inhibitor load, but the effect of aural versus visual task presentation on pupil dilation is unknown. To evaluate effects of presentation mode, pupil dilation was measured in three tasks spanning a range of cognitive activities: mental multiplication, digit sequence recall, and vigilance. Stimuli were presented both aurally and visually, controlling for all known visual influences on pupil diameter. The patterns of dilation were similar for both aural and visual presentation for all three tasks, but the magnitudes of pupil response were greater for aural presentation. Accuracy was higher for visual presentation for mental arithmetic and digit recall. The findings can be accounted for in terms of dual codes in working memory and suggest

that cognitive load is lower for visual than for aural presentation.”
“The purpose of this study was to quantify the reduction in patient learn more radiation dose by X-ray imaging technology using image noise reduction and system settings for neuroangiography and to assess its impact on the working habits of the physician.

Radiation dose data from 190 neuroangiographies and 112 interventional neuroprocedures performed with state-of-the-art image processing

and reference system settings were collected for the period January-June 2010. The system was then SBI-0206965 molecular weight configured with extra image noise reduction algorithms and system settings, which enabled radiation dose reduction without loss of image quality. Radiation dose data from 174 neuroangiographies and 138 interventional neuroprocedures were collected for the period January-June 2012. Procedures were classified as diagnostic or interventional. Patient radiation exposure was quantified using cumulative dose area product and cumulative air kerma. Impact on working habits of the physician was quantified using fluoroscopy time and number of digital subtraction angiography (DSA) images.

The optimized system settings provided significant reduction in dose indicators versus reference system settings (p < 0.001): from 124 to 47 Gy cm(2) and from 0.78 to 0.27 Gy for neuroangiography, and from 328 to 109 Gy cm(2) and from 2.71 to 0.89 Gy for interventional neuroradiology. Differences were not significant between the two systems with regard to fluoroscopy time or number of DSA images.

X-ray imaging technology using an image noise reduction algorithm and system settings provided approximately 60% radiation dose reduction in neuroangiography and interventional neuroradiology, without affecting the working habits of the physician.
