BACKGROUND
Clinicians determine degree of mammographic density based on tissue firmness on breast examination. The study aimed to compare breast density in mammography and clinical breast examination.
MATERIALS AND METHODS
Six-hundred sixty three women 40 years of age or older were studied. The breast exam density was graded from 1 to 4 by two expert surgeons and the mammographic parenchymal density by two expert radiologists. Then for practical reasons, grades 1 and 2 were considered as low-density and grades 3 and 4 as high-density.
RESULTS
High and low densities were detected in 84.5% and 15.5% of clinical breast examinations and 59.7% and 40.3% of mammographies, respectively. The statistical analysis showed a significant difference between the breast tissue densities in breast examination with those in mammography.
CONCLUSIONS
A clinically dense breast does not necessarily imply a dense mammographic picture.
背景
临床医生根据乳房检查时的组织硬度来确定乳房X线摄影密度的程度。本研究旨在比较乳房X线摄影和临床乳房检查中的乳房密度。
材料与方法
对663名40岁及以上的女性进行了研究。两名专家外科医生将乳房检查密度分为1至4级，两名专家放射科医生将乳房X线摄影实质密度进行分级。然后出于实际原因，将1级和2级视为低密度，3级和4级视为高密度。
结果
在临床乳房检查中，分别有84.5%和15.5%检测到高密度和低密度，在乳房X线摄影中分别为59.7%和40.3%。统计分析表明，乳房检查中的乳房组织密度与乳房X线摄影中的密度存在显著差异。
结论
临床上乳房致密并不一定意味着乳房X线摄影图像致密。
