Receiver operating characteristic analysis of chest image interpretation with conventional, laser-printed, and high-resolution workstation images.

摘要: The differences among radiologists in interpreting conventional and digitized images obtained with different radiologic procedures is an important research issue these times of implementation growth the digital modalities. authors performed a multiobserver study to determine performance reading posteroanterior radiographs, radiographs laser printed onto film, displayed on high-resolution workstation (video monitor). A total 300 were evaluated by seven who recorded their ordinal confidence rating presence or absence one more following abnormalities: interstitial disease, nodule, pneumothorax. Receiver operating characteristic analysis showed statistically significant for detection abnormalities individual readers. group as whole reduction observer disease pneumothorax when lase...
