描述了一种一致的、定量的、不依赖于乳腺癌的乳腺X线摄影实质模式的特征化方法。该方法基于数字化乳房X光照片的“分形维度”的计算。评估了基于分形的系统和放射科医生的实质模式分类之间的相关程度。对于一组70个乳房X光片，三位放射科医生在调用Wolfe等级时的平均加权比例一致率为85%，而放射科医生与我们的分形分类器之间的一致率为84%。开发的方法可能被证明是有用的，在建立乳腺癌的风险指数，并最终在确定检查的个人之间的时间间隔在乳房X光检查方案。
A consistent, quantitative, observer-independent method of characterizing mammographic parenchymal pattern is described. The method is based on the calculation of the ''fractal dimension'' of digitized mammograms. The degree of correlation between the parenchymal pattern classifications by a fractal-based system and those of radiologists is assessed. For a set of 70 mammograms, average weighted proportion agreement among three radiologists in calling Wolfe grades was 85%, while agreement between the radiologists and our fractal classifier was 84%. The method developed may prove to be useful in establishing an index of risk for breast cancer and, ultimately, in determining intervals between examinations for individuals in a mammographic screening programme.
