چکیده انگلیسی

BackgroundStable bearing devices are often utilized by prehospital first responders in modern management of severely injured patients. It is not known whether these devices influence radiation exposure or image quality in whole-body computed tomography (WBCT). Additionally, manufacturers currently provide no specifications concerning these criteria. This investigation analyzed the influence of nine different bearing devices on these specified criteria.MethodsThe influence of nine different bearing devices on radiation exposure and image quality in WBCT was investigated. The dose-length-product (DLP100) was obtained through use of a CT-ionisation chamber placed in the centre of a 32 cm CT-phantom and compared with a reference value. Moreover, the results were calculated as effective dose data E (mSv). The image quality was assessed by three expert radiologists using the following scoring scale (0 = no artefacts; 1 = minor artefacts; 2 = clearly artefacts; 3 = massive artefacts).ResultsOut of nine bearing devices examined, four showed significantly higher (2.5–4.5%, p < 0.05) DLP100 and five showed no significant difference between DLP100 and the reference value. The image quality was classified in the categories “0”, “1”, “2” and “3” in 4, 3, 1 and 1 case, respectively.ConclusionsIn diagnostic producers using WBCT, bearing devices may be associated with relevant increases in radiation dose and can affect the image assessability. Some bearing devices are associated with no significant influence on radiation dose and reduction of image quality. Considering all results to get the best balance between image quality and radiation dose, aluminium and metal-free devices should be preferred.
