The digital luminescence radiography (DLR) technique is being used increasingly for clinical diagnosis, particularly in intensive care . Since the installation of a DLR unit, we have carried out more than 20,000 examinations of the chest on patients in intensive care. 12.1% of these were lateral radiographs. In this way, the diagnosis can be made of the extent of a pleural effusion, the presence of a ventral pneumothorax or of atelectasis. Using DLR, these examinations can be carried out at the bedside and have improved the radiological investigation of patients in intensive care.
To date there have been occasional reports on the technical aspects and accounts of the clinical use of digital radiography. There has, however, been a lack of reports on the clinical use of the technique in a large number of patients. We report our experience concerning more than 1250 chest x-rays on patients in intensive care; these have been carried out since December 1987, using a digital system. The method produces improvement in the radiological diagnosis of patients in intensive care; this is due to avoidance of incorrect exposures, the ability to obtain lateral films, consistent exposures and the ability to manipulate and store images electronically.
Vaccination is performed in all groups regardless of the objective risk. The decline in risk perception in non-vaccinated participants might be explained by a defensive mechanism of information processing. Consequently, a strategy of intensified education regarding the risk of disease seems not to be promising in future vaccination projects. Furthermore, it may be more effective to improve the status and importance of vaccination.
Digital luminescence radiography is being increasingly integrated into clinical routine work and is fundamentally suited to replace x-ray film/screen takes. After the necessary optimization of the specific image processing procedure we examined the diagnostic efficacy of this method in respect of phlebography of the leg. If the radiation dose was reduced by 47% in relation to the reference system, the usefulness of the findings in arriving at the diagnosis was by no means reduced under the conditions of high contrast that apply in phlebography, but there was also no additional advantage in respect of diagnostic accuracy. The technical advantages concern mainly the absence of wrong exposures, the possibility of subsequent processing of the image to improve the image quality, and digital storage.
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.
