Additionally, in our subgroup analysis, conspicuity aids appear to be less effective in Auckland compared to other regions.
There was no significant difference in streak artefact or contrast resolution scores between ASiR-70 and ASiR-90; therefore, the images reconstructed at a slice thickness of 5 mm with 70%% ASIR were chosen as the LD-CT data set with optimal image quality and were chosen for the clinical analysis of stone conspicuity (Fig. 2).
A composite measure of physical conspicuity was created using latent class analysis based on the use of fluorescent colours, lights and reflective materials, and the main colour of top, helmet and bike frame.
As it was not possible to categorize crashes by lighting condition, this analysis used a composite measure of conspicuity and found no significant association with the risk of crashes involving a motor vehicle.
This increased contrast on low kVp images has proven beneficial to improve the conspicuity of vascularised abdominal organ lesions independently of dual-energy analysis [51].
To assess the impact of changes in cycling exposure and use of conspicuity aids during follow-up on the association estimates, latent transition analysis (LTA) was first performed using PROC LTA and patterns of using conspicuity aids at two time points (at baseline and in 2009) were examined.
This article attempted to address these issues by using longer-term outcome data (a median follow-up of 6.4 years cf. 4.6 years in the previous analysis) and by creating a composite measure of physical conspicuity based on a set of seven variables.
In particular, tumour conspicuity was enhanced in two cases where image degradation by motion artefacts made data interpretation challenging to conventional analysis.
The arterial phase of enhancement was used for volumetric analysis of hepatocellular carcinoma, and the portal phase was used for metastases because it allowed for the greatest conspicuity.
The stiffness and conspicuity of the tumors as depicted on ARFI elastography and the echogenicity and conspicuity of the tumors on corresponding B-mode images were analyzed.
Several means of improving motorcycle conspicuity in car DRL environments are discussed.
