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.
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.
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.
A clinically dense breast does not necessarily imply a dense mammographic picture.
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。
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。
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。
临床上乳房致密并不一定意味着乳房X线摄影图像致密。
