The results show the feasibility of a low-dose CT protocol at 10 mAs for follow-up of lung nodules. Computer-aided volume measurement in follow-up of lung nodules decreases interobserver variability.
Surveying the literature, gene frequency data on 10∼18 protein loci were collected from six caste populations of north India as well as from two linguistically different populations (Marathis and Gujaratis) and two migrant populations (Parsis and Iranis) in west India. The average heterozygosity per locus of protein loci in all these populations is found to vary from 8 to 11%. The gene differences between individuals from different populations are only slightly higher than those between individuals from the same population. Only 1 % of the total gene diversity (heterozygosity) is attributable between populations.
Sensitivity for lung nodules was significantly enhanced by Gunnar eyewear (+3%), while lower image quality (40 ref mAs) had no impact on nodule sensitivity. Not using the glasses had a bigger impact on sensitivity than lowering the image quality.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
