This study intended to investigate the optimum conditions for lumbar test that has the highest level of irradiation conditions among general test sites. To to this, the most widely used irradiation conditions in terms of statistics were set as standards; test groups applied with DMF were selected; tests groups suitable for clinical trials were selected by using suggested patient dose. Blind tests were conducted by 10 specialists and radiologists. The results suggested that under the optimum conditions, the radiation dose reduction of 2.09 mGy, 4.42 mGy and 3.65 mGy can be achieved in forward-backward test, lateral test and 4-direction test, respectively. There is a need of further studies on the optimization of irradiation conditions in accordance with the conditions of patients. . 과거 아날 http://dx
In this study, human head-mimicking phantom was developed for brain disease treatment study using focused ultrasound. Acoustic parameters of skin, skull and brain were investigated through literature investigation and adequate substitutes according to each tissue were suggested. In the case of skin phantom, construction ratio of glycerol-based TMM phantom was controlled to mimic real skin. The suitability of skull substitutes was evaluated through measurement of acoustic parameters. In the case of brain phantom, transparent egg white phantom was used to observe thermal properties of focused ultrasound. Combined human-head-mimicking phantom using each substitutes was fabricated for development of brain disease treatment protocol. Denaturation of brain phantom according to ultrasonic condition was observed for validation.
Prepared her for the early detection of the risk of cardiovascular disease prevention for the various attempts being made ill through a lot of research to the criteria of coronary artery calcification, but the figure is more than 100 the progress of the flow can be expected to bewas. In this study, we quantify the correlation between body composition analysis, blood lipid levels of calcium and public asymptomatic even at low calcium levels in comparison with the existing studies by analyzing potential risk of cardiovascular disease will be represented on thewere evaluated. Studies, the calcium scores in the body composition analysis "1-10", and when "11-100" when there was a significant correlation in BMI and WHR look more normal frequency range of the mean values in the normal range meomulreoteuna 21% relativeHDL and TG in lipid profiles, no significant correlation look more normal frequency range of risk were derived from the mean values in the normal range, 21% to 40% of the relative risk were derived. meomulreoteuna. In addition, there is no correlation between BFM and BMR Also, average increases in the frequency of a higher standard was higher relative risk derived 31 to 93%, and geological correlation test TC above 20mg/dl atherosclerotic sclerosisseems to be the value of HDL to act to remove cholesterol from atheroma already looking at the same time to suppress the occurrence of atherosclerosis, increased LDL showed higher values occurs rapidly increasing. At this time, the relative risk of 43-50% have been identified. In other words, even when calcium levels are low, that is inherent in the incidence of cardiovascular disease was unknown.
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.
