VALUE OF THE ASYMMETRIC FILM-SCREEN SYSTE M INSIGHT HC IN CHEST IMAGING

The asymmetric film-screen system InSight HC represents a development to optimize chest imaging. The purpose of the study was to compare the exposure range and the image quality of this new system with a conven tional film-screen system. The optical density of images in both techn iques was measured and the image quality of 100 chest images from 50 i ntensive-care patients was evaluated. 4 observers graded the image qua lity of organic, non-organic and pathological structures. Statistical evaluation was performed by interobserver analysis. The asymmetric fil m-screen system shows a larger exposure range and a superior image qua lity in the mediastinal field. The image quality in the peripheral fie ld must be judged critically and improved especially because of the po or recognizability of pneumothoraces.
