Ih. Vanschelven et al., A ROC STUDY OF AMBER AND CONVENTIONAL CHEST IMAGING IN THE DETECTION OF SIMULATED INTERSTITIAL LUNG-DISEASE, European journal of radiology, 21(1), 1995, pp. 67-71
Purpose: The aim of this study was to compare the detection of simulat
ed interstitial lung disease with Advanced Multiple Beam Equalization
Radiography (AMBER) and conventional wide latitude screen-film radiogr
aphy. Materials and methods: Interstitial disease of varying severity
was simulated with overlays on an anthropomorphic chest phantom. A tot
al of 60 images per modality was used in a Receiver Operating Characte
ristic (ROC) study. Results: AMBER performed significantly better than
conventional radiography for all readers (P < 0.02). The difference w
as even more significant for the radiologist readers (P = 0.001). In e
ach case the difference in ROC areas was between 5% and 9%. Conclusion
. AMBER is superior to conventional wide latitude screen-film imaging
in detecting the subtle patterns used to simulate interstitial lung di
sease.
