Color mammography. Image generation and receiver operating characteristic evaluation.

摘要: Boone JM. Color mammography: image generation and receiver operating characteristic evaluation. Invest Radiol 1991;26:521-527. mammography is a technique whereby dual-energy mammographic data are used to calculate calcium image; the colorized overlaid onto conventional (lower energy) gray scale mammogram for radiologist viewing. This presented as practical way use increased sensitivity of without requiring an increase in number images that must read, subjecting unfamiliar appearance subtracted images. Using straightforward imaging theory, acquisition techniques both were optimized, optimal factors generate series computer-simulated (ROC) comparative study. Ideal observer ROC experiments indicate (dual-energy) yield consistently higher specificity presence calcifications, regardless amount tissue “clutter,” whereas results show degraded detectability performance contrast increases. human observers viewing simulated images, color delivered greater calcification than mammography.
