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

    Abstract:
    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.
