[ROC analysis comparing screen film mammography and digital mammography] (original) (raw)

Journal de radiologie, 2000

Abstract

To compare the diagnosis performances of radiologists on screen film versus digital mammography. and methods: Two sets of 123 mammograms, screen film mammography and storage phosphor digital mammography, are studied comparatively with ROC analysis. Phantom study show that conventional method give better scores for usual tension but the detectability of smaller microcalcification is equivalent. To obtain with digital technic the same conventional score you have to increase the radiation dose. Roc Curves, simulated "detection" mode showed that radiologists performed with higher accuracy with conventional system but this difference is weekly statistically significant. ROC Curves, simulated "diagnostic" mode showed the same results wit no statistically significant difference but when the decision to go to the biopsy is the gold standard, ROC Curves were essentially equivalent for both film screen and digital mammography system. The readers consistently considered the...
