[A comparison of digital luminescence radiography and the conventional film-screen technic in pulmonary coin lesions--a clinical study].

The aim of this investigation is the evaluation of DLR for the radiological diagnosis of intrapulmonary coin lesions. For this, a DLR system was used which had been specially developed for chest radiography. Early results were unsatisfactory and therefore specific image parameters were developed. The scope for dose reduction was also investigated. Oncology patients were examined by DLR and by our reference system. Results show that DLR is better than conventional images if edge enhancement is carried out, using the specific parameters. The superiority of the optimised digital images is apparent particularly in those portions of the lung that are obscured by the cardiac or diaphragmatic shadows. Because of image noise, a dose reduction of only 28% is possible, compared with our reference system.

[Clinical and technical experiences with digital luminescent radiography in phlebography of the leg].

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.

[The lateral thoracic radiograph in the intensive care unit using digital luminescence radiography].

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.

[The chest picture in the intensive care station as visualized by digital luminescence radiography].

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.
